Regretting picking one of my bridesmaid

So we been best friends for 11 years but we fell out last summer because on my birthday she decided to start some

Bs, here is a little back story she was in a relationship for 2 almost 3 years and just constantly complained and wasn’t happy, kept going back and forth if she wanted to leave him or not and that was the same thing for almost 3 years so I told

Her I didn’t want to talk about it no more until she came with a decision, so my birthday came around she came and started mess saying she hate me, jealous, don’t like me, and felt like I was taking her shine a way so I dropped her, well fast forward to now I started back being cool with her thinking maybe she changed but she hasn’t because she seems uninterested in my wedding and just irresponsible, I feel like we are on two different pages in life but my question is how do i let her know i don’t want her as my bridesmaid? Or do I just stuck it up until after my wedding ?
