Need opinions!!

Sorry for the ridiculously long story BUT opinions PLEASE....... I had my wedding scheduled for this past August, but had to reschedule. It's suppose to be this upcoming summer. It's been almost 2 years now since the start of planning. I asked some old best friends to stand as my bridesmaids. They were all more then thrilled, but never really even reached out to me prior since higschool. I guess I didn't realize till recently I was trying to hard to keep them around when I should have just let them go. When it came time to get their dresses, I allowed them to pick their own, and asked if budget was an issue. 2 ignored and the other 2 said there was no issue. I scheduled the appointment about a month in a half in advance based off everyone's availability, and when the day came they all tried to back out. One girl specifically had been ignoring me for some time. I privately messaged her, asking if there were issues, and politely if it was in her best interest for the both of us if she was sure she wanted to stand. (She was having some private personal issues). She blew up, saying I'm cornering her and making everything about me? She ended up getting her dress, but it was the first dress she tried on and didn't seem in the least interested in the appointment. She later told me she couldn't pay for it, and I offered help and she ignored me. It has now been over a year since I seen her, and the dress is still sitting at the boutique. She hasn't made any payments or arrangements on it, or even notified me that there's a reason for her lack of concern. I have tried to reach out to her multiple times, only for the messages to be read, and then ignored. She is very active on social media. Her, along with another bridesmaid, have been ignoring me since their appointment. I was in a bad car accident a few months ago and they didn't even reach out. My fiancé and I have made the decision to cancel the wedding very recently. Family and friend drama has been ridiculous in the planning, and we have decided it's best to do something for ourselves rather then spend all this money pleasing people that don't seem to care (We are thinking elopement) I have doubts, and concerns on how I should approach this, I am easily manipulated and feel I have really had this experience taken out from under me from the selfishness of others... One bridesmaid dress was 200 and the other girl only paid half of hers when she had to order....Do I owe them a refund?
