Keep my bridesmaids?

I’m getting married in May 2022. There’s still ample time and I like to take things slow. I battled cancer for 2yrs now & was recently diagnosed with a heart condition and I have to mind my stress. So, needless to say, I slow down for my health and to appreciate the little things during the planning process. My FH helps me a lot. So, I originally had my cousin as a MOH and 2 friends as BM. My cousin who broke up with her bf began to change and insult me any chance she could. And not just me but also her family. After I tried sitting with her to talk to her, I got two words in . So I gave her space. 2 months later I have her and my 2 friends meet over dinner and she proceeds to insult me again, and my BM stopped talking the rest of the night. So I dropped my cousin after she told me she wasn’t going to do anything. (That was last yr) this year, my 2 BM broke up with their BF, (the girls broke it off with the boy, not the other way around), in June. Since then, they stopped responding to me and hang out with themselves now. I introduced them to each other and now I don’t get invited to see them. I only find out they’re out because they post it on social media. I’ve been there for both of them for the past 4yrs. Even when they were having boy issues and they needed someone to talk to, I ALWAYS picked up the phone or drove to see them (and sometimes while I had my cancer pains). I did give them my concerns. How I don’t want this to just be a ‘bridal party’ I want this process to be a unifying/friendship building experience. But it seems like it’s only for them. I reach out to schedule a day out with them once a month since they said 2-3x a month is hard. And even then, I get told no, but they end up hanging out? What’s up with that? I’ve asked if I did something and they said no, we’re here for you. I haven’t even asked for help with wedding DIYs. After their break ups, they went from being caring friends(who I occasionally got to see… to attention seeking/ half naked social media girls. And they’re starting to throw in directives at me about how I’m getting married and they’re not. Do they fail to see I almost died and this is a good thing happening for me? What happened to friendship and caring for one another and genuinely being happy for your friends. Am I wrong for asking for friendship with them or am I reading this right?
