In my position, ideally for my wedding id want both parents there but my mum won't go if my dads going. My SOs parents arnt together either and they wouldn't like being there together either but his parents would deal with it because they are adults 🙄 unlike my mother who will not go if my dad does! We are thinking maybe we will just have a quiet wedding with hardly anyone, maybe a few people and then do a big shin dig party after where everyone is invited. My mum would probably not attend that. Maybe just invite our mothers for the wedding and everyone else for the after party?
