Just want to vent

Hello all,
I hope the holidays have been good for all of you.
A lot has happened over the last few months as I tried to plan my wedding. We were going to have a “big” wedding 07-01-22, booked the venue, photographer, and wedding planner. But I sadly had to cut my toxic dad and his entire side of the family from my life in order to protect myself. To keep it short, they tried to force me to see a family member that sexually abused me for years growing up. They’ve always tried to make me see him but they got ugly about it this time and I couldn’t take it anymore. My father said the abuse wasn’t his problem and that I should make things right with my abuser. Family is supposed to protect you but I was being put in harms way. It’s been a very difficult adjustment as I grieve losing them. I was never close to my moms side of the family either, and now I have nearly no family in my life.
My dad was going to finance my wedding however that is obviously no longer the case. The last thing I want is for him to use it as leverage against me or feel he’s entitled to invite my abuser, so my fiancé and I will have to sort things out financially ourselves. This is difficult because we are also trying to purchase a house next year.
I’m just venting/explaining my situation because I feel very isolated, down, and hurt over what occurred with my family. Our wedding will be much smaller than originally planned but im afraid my in-laws will criticize it. They’re accustomed to having large Catholic weddings with party buses, expensive food, open bar, etc. I’m not Catholic nor can I afford a celebration that elaborate. I honestly don’t know how to feel about planning anymore. I know this just about my fiancé and I celebrating our commitment to each other, but I can’t help but feel down about it. I hope you all are doing well and have the wedding of your dreams. If any of you need someone to talk to please reach out!
