AIO My sister and husband text privately and spend time together. Should I be concerned?
My husband and my sister have developed what I think is an unusually close relationship, and I’m trying to figure out if I’m overreacting.
My husband travels for work to the area where my sister lives, so they have opportunities to see each other when he is in town.
Some examples:
They text directly about travel plans, shopping, TV shows, and random family/life stuff.
My sister has gone shopping one-on-one with him before and bought clothes for him because she remembered his size.
She frequently sends me photos of outfits, earrings, dresses, etc. asking for my opinion, but often it feels more like she wants validation than advice.
Once she modeled a dress in front of me, my husband, and her husband. Her husband complimented her, but she immediately asked my husband what he thought.
She has privately texted my husband asking when he’ll be in town and told him when she would be away, seemingly so he wouldn’t visit when she was gone.
When my husband mentioned a possible birthday-week visit, she got very excited and immediately said she would start looking for reservations.
She often seems unusually interested in my husband’s reaction to clothes or style choices.
My husband says nothing inappropriate has happened and that it’s all harmless.
Am I overreacting, or does this sound like emotional flirtation / blurred boundaries? If you were in my shoes, would this bother you?
Note: There were over 100 replies from OOP across multiple subs, i've convetred them into Q&A
Have you talked to your husband about how uncomfortable this makes you feel? >Yea once I kind of hinted at something kind of mild like what are you texting so much about and he said “relax”. > >I have not flat out called him out on it. Just every time I remotely suggest something he either ignores my comment or dismisses it. One time I brought up going with he did not shut it down but then it turned into oh I will be going for only 1 day quick turn around.
Have you read their messages? What did you find? >Yes I have and they both seem complicit. Its like watching a tennis match with the texts back and forth inside jokes but nothing obvious like everthinh has some > >Plausible deniability. > >They did but one could read them and think nothing obvious > >Great advice! Some of what I have seen in texts spills into her making minor annoyances about her husband or issues with the kids but nothing openly blatant. But I can’t say I have seen all their texts. I also don’t understand why they have a private lane when in other instances I’m in chats and it’s usually when she’s sending photos of herself. If she sent that in private it would be an open flag but instead all > >Those texts include me.
Do they spend time alone together? >He works quit a bit. They do things together with him but seems like a a lot without him. Also the texts never mention him in the plans. Like he will meet her at a mall just the two of them spend time together then meet him. > >They mostly hang out alone then meet up with BIL but it’s so orchestrated to avoid him. > >Thank you this is helping at least confirm I’m not insane. As to your question they never tell me ahead of time. But one time he left his busness meeting early i could see he was heading tomher neighbohood. I called multiple times and he did not pick up. Later it came out they met up for coffee hung out shopped and then met her husband for dinner.
Does the texting increase around his work trips? >I feel terrible for saying but I check his phone. Aside from a few blips once a month a funny clip and small chat it ramps up just before one of his trips. > >Not so much missing sections if anything the texting escalates when he’s there and I’m > >Going to sound insane but feels like they are giddy and trying to find ways to get together. On one shopping excursion she had him take pictures of her trying on clothes. Nothing too sexy mostly winter clothing but she got all her make up on and hair done up.
How often do they shop together? Does your husband even like shopping? >They went shopping together multiple times and always alone. > >He hates shopping that’s something I did not connect the dots on I have to pull teeth and yet every time he’s out there they just happen to end up at mall together.
What does your brother-in-law know? Why haven't you talked to him? >Yea she’s married I don’t know what he thinks worried if I say something to him I might escalate and everyone will think I’m Insane. > >We are all in our 40s. Her husband and don’t have that kind of open line of communication and he certainly has not hinted anything to me. He kind of worships her and does whatever she says. So not sure if the light bulb is not going on but I can’t go to him about this without more concrete evidence. It’s hard to explain I worry I will look like an insane possesseve jelous person and im not but all of it seems > >Just off without a real smoking gun. They both play it like this is just normal. > >No bc i know based on our relationship she will 100% say im insane and jealous. As for her husband i dont have a read on his take and it could get ugly fast if im reading this the wrong way.
Why do you believe your sister wants your husband's attention? >He has control of his travel schedule to a certain extent. She will include him on some of the photos. They would include her husband but why not include him in the texts for celebration. Her text are always like it’s bw the two of them. Like they are playing a couple. He doesn’t hide them but as I said they have this plausible deniability something feels off but I will look like a jealous B if I say something that’s the difficult part. > >I never ask her husband. One time she tried two tops asked all of us which we Liked better we all gave response my husband mentioned the one the others voted down she wore what my husband picked and then I caught her saying to him see what I picked.
Did your sister invite your husband to stay at her house? Do you think they're having a physical affair?
>He stays at hotel but I found a private message where she told him he should stay at their house. > >He said thanks but I need to be close to the office. > >The shopping started about a year and a half ago. But I don’t think they having physical intimacy I think it might be emotional and could get to the physical.
Has your sister always been competitive with you? Why haven't you confronted your sister?
>Older than me and yea competitive > >She is going to say I’m insecure and crazy

AIO UPDATED-My sister and husband text privately and spend time together. Should I be concerned?
Since my last post, I found out more context that made me feel even less like this was “just one weird moment.”
I learned from my niece that during the purse-shopping trip, my sister encouraged her son to leave and go with his sister, which left my husband and my sister shopping together. My husband then took multiple photos of my sister trying on purses. My niece also later mentioned that the sales associate assumed they were husband and wife. My sister corrected her, but apparently found the whole thing funny and entertaining.
I’ve seen the purse photos now, and they do not feel like “quick shopping reference photos.” They feel like my husband photographing my sister modeling.
There was also another visit where my husband stayed at my sister and her husband’s house. After her husband left, my sister did her hair and makeup, modeled a winter coat, and my husband offered to take photos so she could see it. Later that night, when she was dressed up for an event with her husband, she sent my husband a photo of herself with no comment attached.
Again, any one thing could maybe be explained away. But added to the private texting, the skirt saga, the jeans gift, the dress/top opinions, the way she seems to care about his reaction to what she wears, and the fact that she keeps creating these little moments where he becomes her photographer or appearance judge it started to feel like a pattern I could not unsee.
So I talked to my sister first.
I told her I needed to discuss something awkward, and I tried to be calm. I said I was uncomfortable with the texting, the outfit photos, the shopping, and the way she seems to use my husband as an audience for how she looks.
She immediately got very calm. Almost too calm.
She said, “He’s my brother-in-law. We get along. I didn’t realize that was a crime now.”
I told her it was not that they get along. It was how they get along.
She asked, “How do we get along?”
I said, “You use him as an audience.”
That was when her tone changed. She gave this small smile and said, “Or maybe I’m just comfortable in my body and you’re uncomfortable watching someone else be comfortable in hers.”
I told her that was unfair.
She said, “Then what exactly was I doing? Modeling too aggressively? Wearing leggings at you?”
I said I was trying to set a boundary.
She said, “No. You’re asking me to shrink so you can feel bigger.”
That one really hurt.
When I brought up the photo she sent him after the coat situation, she said, “I sent a photo in a conversation we were already having.”
I said, “With no comment.”
She said, “Because it didn’t need one.”
Then she said, “Maybe you should try sending him photos. Maybe then you wouldn’t be so worried about him looking at mine.”
I told her that was unnecessary, and she said, “So is accusing your sister of trying to tempt your husband because he took a few pictures while shopping.”
I asked if she would stop texting him privately about clothes, outfits, shopping, and photos.
She said, “Stop what, exactly? Existing around him? Being friendly? Letting him take a photo if I ask? Laughing when something is funny?”
I said, “You know what I mean.”
She said, “No, I don’t think you know what you mean.”
The conversation ended with her saying, “If your issue is with your husband looking, talk to your husband. If your issue is that I look good, that’s not mine to fix.”
That was probably the most painful part, because she made me feel insane and jealous for noticing something that still feels real to me.
She did not apologize. She did not agree to stop. She basically framed the entire thing as my insecurity and said I was trying to control a normal family friendship because I felt threatened.
I walked away feeling worse, not better.
And honestly, that conversation left me more confused.
So now should I have a conversation with my husband….? wtf do i say I thought confronting her with the facts would be easy but I felt stupid petty and jealous. I need a sanity check.
COMMENTS
Lanky_Emu_1184 > girl if that was my sister I’m slapping her across the face, but besides that, my sister would never be like that towards me because she doesn’t have this underlying competition that your sister seems to be having with you. Did you guys grow up getting compared a lot? > > OOP >> We did >> >> Noonull >>> Your sister wants the attention you get from him. She might not necessarily want him, she just wants to take what you have or she likes having the ability to do it. >>> >>> Talk to her husband and yours and tell them the boundary. If they are okay with what she’s doing, then you know that you need to pack it up and leave and go NC with her. He should not be entertaining her and her husband should not be happy with her toeing the line. She will escalate it for fun now that she knows you don’t like it. >>> >>> OOP >>>> I think you’re right although she has done a few things that lead me to believe she might be attracted to him.
Suki_13 > NOR. Your sister is a classic narcissist. Personally, the older I get the more I distance myself from energy vampires like this and people who bring nothing to the table, even if it’s family. That being said, I would have a heart to heart with your husband and find out what his motivation is behind all of this and let him know you feel disrespected. His response will tell you all you need to know. On a sidenote, does your sister not know how to use a mirror?! > > OOP >> 🙏🏻and such a good point 🤣
kittendollie13 > NOR. If I remember your original post, your sister was recently divorced or was in the middle of one. She is a shark going after your husband, and she is a conceited b&$"ch. I can't tell just how clueless your husband is or if he is putting on an act but both of y'all need to block your sister. > > OOP >> No she is not divorced or divorcing but don’t know if that’s in the works that she has not told me.
swhertzberg > I feel like there is a big difference between OP's husband using his phone to take pictures, vs OP's sister in law handing her phone to him and asking him to take pictures. > > OOP >> I had not pinpointed this but I think you are 100% on why it bothers me. She’s letting him take photos that he can revisit. That’s going on my list of arguments
