Bridesmaid mistake

So I’ve posted here quite a bit about my troubles with a few of my bridesmaids. Mostly my FH’s sister, FH’s brothers gf and his cousins gf. After speaking with FSIL I think we’re good, she’s just very immature and caught up in a toxic relationship right now so i’ll just hope when she gets older she figures things out. Spoke with cousin’s gf who I was actually the closest with as she lived with me and we had an open and honest conversation. Turns out brothers gf doesn’t really care for me or sees me really as a friend and doesn’t care to try to make it better. Cousins gf told her that she spoke with me and thought it was important that I know how brothers gf really felt and suggested she talk to me herself and she just said okay and that it wasn’t that important. At this point, I have 9 other girls who actually care and only because she’s FBIL’s gf is why i’ll be keeping her in the party, 2 months out is too late to change things anyway. I’ll stay cordial when I’m around her but i’ve given up thinking we could actually be good friends one day. It just sucks because once cousins gf came in the picture I really thought we were getting closer but I guess I was wrong. Since FH’s family is really close and we see them all the time it might be awkward having to be around her a lot but I would rather spend my time with people who actually care about me not someone who is fake and doesn’t care about me at all
