Matron of Honor

My Matron of Honor is making me mad! She hasn't done anything or hasn't part taken in any of my pre wedding events. She was going through a tough time financially the beginning of the year. So I paid for her dress with the intent of her paying me back. This was in January and she hasn't even brought it up or given me the money. She promised she was coming to my bachelorette party. Didn't tell me that she wasn't coming until it became past the time she should of gotten to the cottage where we were staying for the weekend and told me she had a bad day and wasn't going to make it! I told her she probably needed to get away for the weekend and I really wanted her to come. I never heard a reply from her at all after I told her I wanted her to come. I had my bridal shower today and she didn't even come to that either! Didn't even message me and say sorry girl I can't make it. Just silence. She hasn't even asked if I need help with anything or even ask how I'm holding up with all the changes we have had to do cuz of COVID. People think I should ask for the dress back and give her the boot out of the wedding. I just don't know what to do. I picked her to be my matron of honor cuz I thought I could depend on her and she would be there for me. Its just all so frustrating!! What should I do!? Thanks!
