*long post/rant*

So my bf and I been together 5 years now. Recently moved into our first place together. Never had a breakup, big fight, no cheating, etc. not that we’re perfect he’s annoying as hell lol but never anything crazy. So his mom and I were cool the first year or two. Getting our nails done together, shopping, etc. my bf’s brother brought home a girl and got her pregnant literally not too long after. After that it was forget me.. never looks for me, checks on me, doesn’t visit us sometimes not even on my bf but gets mad if he doesn’t call her or go over. His brother and his gf/babymom cause they’re always on/off, cheating, taking the kids away are always needing her help and stuff. He tells me to talk to her about it But all I wanted was for her to genuinely want a relationship with me not because of pity. She’s done shit to purposely exclude me and always has smart comments or what I do, wear etc and my bf doesn’t see it. He says she’s just tryna to be on the babymoms good side so she doesn’t take her grandkids away. But that doesn’t mean she has to exclude me! I haven’t spoken to her for literally a month or more. I never try to exclude her or anything and never disrespected her but im so sick of her and don’t want to put my bf in a position where he has to chose me or her but just defend me! We’re supposed to go over for thanksgiving but I just don’t feel like it. I was going to pretend I’m sick and just have him bring me food lol ugh any advice?!
