My parents don't want to come to my wedding

I need somewhere to vent about this but my parents don't want to come to my wedding, specifically my mom. She has made several passive aggressive comments about how we should elope, EVERYONE should wear black, how she doesn't see a point in going dress shopping with me, etc- she hasn't had a nice thing to say about anything. A few weeks before my fiance proposed, my mom was mad that we wouldn't join her on a cruise at the end of the year with my cousin; I begged my mom not to go in case my fiance popped the question (she knew he was going to) because the wedding (destination) would be between February and April of the following year, so she told me I owed her a family vacation. Fast forward to the proposal and we remind her our plans to have a cruise wedding and she is PISSED because she agreed to go with my cousin and she would be heartbroken if she changed her mind (she has hated her up until last year). My mom has made it EXTREMELY clear that she doesn't want to attend. I brought it up with her and asked her to be honest with me and she/my father proceeded to gaslight me and make weird excuses about why they wouldn't be able to go (Lil sisters will have to miss school, father will have to take time off, etc) and told me not to expect anyone else from my family to show up and that we should just cancel and elope like she originally suggested. My heart is breaking from the confirmation that my parents don't care about our big day and would rather gaslight me instead of admitting they would rather go on a cruise with my cousin. My fiance is going to invite more of his family since mine won't be coming but it makes me feel really jealous that he has so many people that love him while I'm 2nd and sometimes 3rd fiddle with my own family
