I've been training very consistently for 2 years, before that I was on and off. I feel like I should be seeing more growth than I am; right now it seems very insignificant.
I do progressive overload; start with my heaviest weight. I do 3 sets 6, 8, 10. Once my 10 can reach 12 reps or my 6 increases to 8, I increase my weight by 20lbs. I find myself increasing in weight at least once a month.

So I don't know what I'm doing wrong. I also make sure to eat between 110-130/160g of protein as a 161lbs female at 5'7.

I'm wondering if maybe I'm not doing enough volume? I work both upper and lower body twice a week. I also do 20 minutes of incline walking at level 3, 4 days a week after weight lifting.

I (32) have known this man (36) for 6 years now. We've had a relationship, split, friends, fwb, work partners, all that. I do not like dealing with a man who's sleeping with other people. He knows that I've expressed it. So I know I'm silly for being in this situation in the first place.
After the last time I found out about someone else, I blocked him everywhere. But he found his way to me, we spoke, he gifted me as it was Christmas and he helped me when I was going through a really hard time.
He has done a lot for me, he's there for me when I'm in need and I've known him for so long now so I was willing to be friends. However he always wants a little more, he likes FaceTimes, ask for pictures and videos, he likes to talk sex, he likes me to come over to do his hair and have sex when we're done, things like that.
Again I know I'm silly. But because of how he's there for me it's easier to just go with it. But I had a sincere and honest conversation with him twice. I asked him to please just let me know if there's someone else he's interested in and consistent with because the one thing I hate is to be asking for his time just for another woman to not have to ask for anything. Every time we spoke he told me he understood.
I rarely get to see him these days. Twice a month and that's if I start to complain. He use to see me every week. My birthday just passed and he didn't do anything for me. He said his money's low, he doesn't feel like hanging out and I understood. I asked if we could at least spend an evening together and he agreed. My birthday's in May, he only got around to seeing me last week. If I didn't ask he wouldn't have done anything.
Everytime I'm with him I see him texting the same woman. I didn't say anything because when I do try to have honest conversations he gets upset and defensive. So I just let it play out.
Last Tuesday night into Wednesday we spent time together in his home for my "birthday". Sunday night I was informed this woman is posting at his house Saturday night. They seemed to have went out for a night of drinks and then went back to his home.
When I found out I went to him expressed how hurt I was and I wish he would've just told me. He just kept asking me questions back "I took her out?", "I had her in my home?" Until I sent the pictures then he goes on to say he's single and he can do what he wants. Which he is. It's the dishonesty that's killing me. We are supposed to be best friends before anything he didn't have to do this.
He heard me out for a while I'm sure I said things like I'm done with him, go talk to her if that's who you really want.. then of course he got fed up and said he's done talking he's driving and we'll talk later.
I did not hear from him for the rest of the night. I woke up to dms the next day of more of pictures of her in his house again. So after he saw how hurt I was, he did not think about me for a second afterwards. He went right back to ask her to come over again.
I reacted and called him the biggest piece of garbage I've ever met in my life". Even after everything he's done me, this was truly shocking
We went back and forth some more, and he's still important to me so I stupidly still wanted him to make it right. He said because I called him the biggest piece of garbage he's not going to stop talking to her and he's not going to try and make things right. And that he'll respond to me when and if he wants.
I know I reacted out of anger and hurt so I did sincerely apologize but all he said was he read it and we'll leave it as he's the biggest piece of shit.
I feel like it was wrong to say. But I don't feel like it's right for him to hold me to a reaction of something he did. Please I need to know if I'm in the wrong and I messed up. Thank you.

TLDR
AITAH for calling my "friend" the biggest piece of garbage ive ever met after we had an understanding about other women for me to find out he had someone in his home, hear me out about how I feel, and then go back to her instead of trying to make anything right with me?

I really want a pink sandal. I thought I found one on mytheresa and I was about to purchase and the page just vanished; no longer available.

Is everyone doing custom orders? Or do we just wait and search sites until we find something unique we're looking for?

Thank you for the help!
