Wedding trouble 😣

I’m posting this anonymously as I have a few people that know me following me on this. I’m getting married next July (hopefully unless Covid has other plans). My parents have split up 3 years ago and both have new partners and moved on with their lives however they are still on really bad terms. My dad did contribute some money (probably about 20% of the whole cost) towards the wedding and is planning to continue to do so but he said he doesn’t want to see my mum at the wedding. It came as a huge shock to me but I have no idea what to do.

Obviously I really want both my parents at the wedding, but every time they see each other it just ends in one big fight. I do really want to keep both of them happy but it just doesn’t seem like there’s a way to do that. Any ideas of what I could do? My mum isn’t very confrontational it’s mainly my dad but she will retaliate. I really don’t want to exclude people as I love both my parents equally but I dont want my big day to be ruined with their fights, as that would not only upset me but also would be quite embarrassing for me as my parents family and our friends will all be there.

I was really looking forward to our big day but at this point I just feel like crying and not doing it anymore. I just feel like I’ve really hit a wall and there’s not a single good way to get out of this situation. I’m really considering just ditching the whole wedding and it just being me and my partner. But I also will feel quite stupid for cancelling as everyone knows about the wedding and has been practically invited.

Any advise please😣
