Bridesmaid drama update, another one bites the dust

I had posted last month about some issues with a bridesmaid. We’ve been friends for a while and things are extremely one sided. I’ve been there for her through everything, every event. So long story short the entire year and a half she hasn’t answered any messages from my MOH and only will go through me. She literally just ignores her. Events have gone like this:
-engagement party: invited her and her entire family because I know she has social anxiety and I wanted her to feel comfortable. She ran inside (late), said hi to me, and then left immediately without saying anything.
-dresses: she refused to try on dresses with the bridal party (for no reason other than not wanting to) and made me drive an hour away separately 3 times to go with her by herself. Whatever, I didn’t complain.-bridal shower: had to be rescheduled due to Covid. My mom is planning it from across the country so she needs their help. She texted my bridesmaids simply confirming if the new date worked for them and she never answered her. My mom even texted her separately, still nothing. I texted her asking if she knew the new date, she said “she’s too busy to worry about it right now”-bach: she agreed to go, paid for half of what she owed, it got closer and she dropped off the face of the earth. No one including me had heard from her in weeks, no money, nothing. Multiple texts trying to confirm and nothing answered. She texted me out of the blue that she was going through some stuff with an ex, and then never answered again. We get to the bach weekend and my moh texted her asking if she’s going to show up, SHE WENT OFF ON HER. Told my MOH she’s got better things to worry about than this, and she doesn’t need this drama in her life. Also that it was my fault for not telling them she’s going through something with her ex. I’m just over it. I don’t care to be friends anymore either after all of this. It’s shown true colors.
Point is, after I saw that text I blocked her on everything because I was so hurt. I know I need to tell her she’s not in the wedding anymore, I’m just not sure how. She also already bought a dress, which I don’t mind sending her the money back for but also feel a little weird about it because she didn’t have the decency to even respond to my mother. Opinions please
