I’m stuck. long Rant!

I love my fiancé and I want to marry him but I don’t want this wedding. It’s not what I want or envisioned. I tried explaining to him before we started the planning process how stressful and aggravating it will be for me. Both my mom and sister are in the wedding business, so I have a great idea beforehand, how it would be. He WANTED a traditional wedding. (Cultural and other reasons.).
Relationship are about compromising, right! Fine, so I said, then we will have something intimate. We are at 130 ppl and still going up. My family is huge!
I wanted a different venue, but my fiancé begged me for another venue. Everyone who has seen it, has agreed I shouldn’t have compromised on that. It’s just mediocre with an ugly carpet. My mom and sister had pretty much designed the wedding and changed everything that I wanted, down to my COLOR SCHEME, CENTERPIECES, napkins, silverware. EVERYTHING!! Nothing is my idea. I wanted a cake swing, my sister insist I do a dessert table.I feel both my sister and mom, feel like pressure is on them because they are in the business. I also Know neither one of them had the wedding they wanted and I they are using my day as a rebound. My sister and I have even gotten into a huge argument at the venue because she wants me to have chairs that I can’t afford. That hasn’t slowed her or my mom down. Yes having 2 close family members in the wedding business has helped but it really doesn’t matter if my WHOLE vision is changed. I have been ready to throw away the whole wedding and go to the courthouse, but I CAN’T get my $1000 deposit back, and I would have to pay an additional $3k for breaking the contract.
