So a pretty quick background we dated for 8 months, he proposed to me in private, then I found out he was cheating lying and a whole bunch of other stuff.
At the end of it I was going back and forth between staying with him and his family and staying with my own family, he then turned to god started going to church, went on some beach trip, came back and came to my place three nights in a row. We “made love” and then he said he had to leave each night and get home.
The following weekend he broke up with me claiming that maybe god would bring us back together eventually and that there was no one else he just needed to work on himself.
He then posted that they were dating 11 days later, and engaged just 2-3 months after the breakup.
Weve been broken up for about 6 months and they’ve been together for that long.
Welp today I decided to check his Facebook for some reason, he has me blocked so I just searched his name up without logging in.
I then saw the pictures. He had taken pictures of them together on the beach and some just of her and posted them right after our breakup. Meaning that we were still together while he was doing this. He also posted picture of them in her apartment that he moved into immediately.
I then saw a wedding registry for them. So I decided to buy them a gift :) just sent $1 towards their adventure funds and left a note saying “Cute Beach Picture. I wonder when those were taken :).”
Now I’d consider this a form of revenge because he claims hes told her the entire truth about every single thing that happened, and because of the ways he treated me. It may be small revenge but it’s petty revenge.
He’s not a very techy or good with his phone type guy so I’m sure she’ll see the email for it before he does.
But anyway that’s my quick little petty revenge story.

So my friend F22 (Sarita) and I F21 (Friends for over 15 years) wanted to have a Barbeque at my place which happened Saturday, so we had her mom get some stuff for it and make food/drive her over etc. I gave her gas and sent her with money and told her if there wasnt enough to just not get the extra items. She bought more than I asked her too, spent some of her own money, then expected me to pay her back. I told her I could becasue I felt bad and then paid her that amount. Come the day of the party I told both of them I could pay them back for what they bought that day, and to let me know the cost. Sarita told me I didn’t need to pay her back. Kim however did want me to. So I told her I could the next time she came over as I’m the only one with money sending apps and she rarely comes out my direction. She didn’t ask for the money that night, as I didn’t have it, I explained that to her, and she said it was fine and I could pay her back later. Sarita and I were on the phone, Kim came by, I said Hi to her, and the first thing she asked was when I could give her the money. (She never let me know the total.) I told her I had it and could again give it to her later. Sarita and I then planned to hangout again on a Monday and have Kim bring her. At this point I believe it was Wednesday. My place is about 30 min from hers, but she always asks for $20 to come out claims she can barley make it on that, and had been asking for cans and money from people because she was so low on gas. (She has no job, constantly asks Sarita for money, gambles or buys alcohol with every dime she gets, and forced saritas dad to buy her a car before Sarita after her father said he wanted to buy Sarita one) I was only going to pay her $20-30 as she never told me how much she spent, and I told her that was how much I could giver her. I then had to buy animal feed which made me decide I was giving her $20-25 as I cant cut into my saving too much. And I didn’t think it could have been over that. I knew if I gave her anymore she would spend it on beer or slot machines. (Sarita and ger split the costs and bought, glow sticks, chips, solo cups, and ping pong balls and we already paid Kim $40 in gas and $20 extra to go to the bar.) We had also offered to give her gas when she brought Sarita out so she would be making more that day. Now it’s Friday, Sarita gives her mom $20 for gas after her mom offered her a ride and never mentioned money until she was there to get her. Sarita had also just let her mom know how she was trying to save money and needed to buy essential items for herself. She also never once mentioned to Sarita that the dog needed food. All did she was ask for gas money after offering her a free ride to work. She then later texts me asking about the money again, I again asked her to wait until she was coming out in a couple days as it didn’t make sense to drive out here on gas from cans, put the money in her tank, then have nothing left when she got home and again have to beg for more money/cans. She then blew up saying, “Ok but in the meantime Sarahs's dog will be outta food so if that's what she wants then that will be how it is! Kinda funny how I'm the one with the car but I'm being told when and where to go!” (Deadnaming their own child). So I text back saying, “Yes. I have $20 for you, but it doesn't make sense when you're already low on gas to come get that until you're already coming out this way. When you always need $20 in gas to get here.
That's also ridiculous to try to hold that over mine or your own flesh and bloods head. You got buster when Sarah was a CHILD. Meaning it's your responsibility to feed that dog. A child does not have a real choice.
The PARENT does. I would walk miles in the blazing hot sun to get my dog even a shred of food if he was starving.
Also thank you, it's extremely comforting to know how you actually feel about me. And that you judge your own child and I for not having a vehicle after the shitty lives Weve both been forced to live.”
Sarita isn’t mad at me, but her mom has continuously tried to tell her that I’m a terrible influence, leading her in the wrong direction, and that is playing video games together every once in awhile is bad. We mostly garden or play with the animals I have, will drink and play video games for a couple hours occasionally. So when I heard that I did have to cackle at it.

So AITA for telling her to wait when she needed it?

Edit: Sarita and I are both out of vehicles atm which is why her mom did anything in the first place. Never once did I see her mom nor did she ever drive anywhere remotely close to where I live. She had been so low on gas that week that she had run out multiple times, and if she drove to me she would have run out on the way, or on the way back home even with the money from me. Which is why she was asked to wait a couple days when we'd be able to give her $40-60. She also never once mentioned to Sarita that the dog needed food, me showing her the text her mom sent was the first hearing that he was out.
Also the names are fake, and I ran this by first, she saw the “deadname” part and still told me this was fine to post
