wedding off... bridesmaids

My fiancé and I had our wedding set and planned and everything paid for for August of this year. Everything was done, all that was left was to walk down the aisle. But then my fiancé decided randomly (randomly to me at least) that he didn't really love me anymore (we were together over 5 years) and he left me about a month ago. So my family and I lost out on a lot of money we spent on the wedding. He's paid some of it back to me at least but not a lot. Anyway, my bridesmaids had all bought and paid for their own dresses. When this first happened and we broke up I was so shocked and embarrassed and felt bad and I did tell my bridesmaids I would work on trying to get them their money back for the dresses. I had 4 bridesmaids and 3 of them told me to absolutely not worry about paying them back and that it wasn't my fault at all, etc. the 4th one keeps hounding me about it. Which I totally understand, because I know it was money out of their own pockets and I did say I'd try as hard as I could to try and get them the money back. I also found out I'm pregnant (11 weeks) and now living on one income, it's just a rough time all together having to adjust to a completely new life and I wish my one bridesmaid would leave me alone about it and be a little more understanding. I can't make extra money appear out of thin air and I feel like she's not being a real friend. Of course I feel bad and I intend on keeping my word but idk what to say or tell her. Just wanted to vent. 😞😞
