Brother getting married August next year, recently announced. We get on and I love him but I don't want to go to the wedding. I'm in Yorkshire, he lives in the Scottish Isles which is where he's getting married. Meaning I'd have to stay over minimum of 2, probably 3, nights just for travel purposes. I'm a single mum (with a boyfriend who I don't live with and who hasn't met my kids as it's only been 5 months) with 2 kids, and it's a child free wedding. I've already planned summer holiday contact time with exH (he's abroad with his GF on that date) and the wedding falls on my dates. Everyone I'd pick to watch them for 2/3+ nights will be at the wedding!
If kids were invited I wouldn't have taken my boyfriend. I don't plan for him to meet the kids, let alone spend a break away with them, anytime soon. But I don't want to go to a wedding on my own either.
But the big reason is, a family member who sexually abused and raped me as a child will be there in the wedding party, making a speech too. The thought of me clapping eyes on him as everyone applauds him makes me feel sick. Ive never been to the police or anything, my mum knows about the abuse (and has done nothing about it) and so do a few people like close friends and my boyfriend but nobody else does. Not my brother or siblings.
My family (mum and siblings) think it's awful that I won't even attempt to make childcare plans. I have good friends I could leave my kids with, but I don't really want to TBH. They will be 6 & 10 and I think it's just too far with no parent nearby for that long. They say I'm being precious 
My boyfriend thinks me and him should just go, and that I should be 'brave' and 'face my abuser'. I'm actually really REALLY wound up that he just doesn't fucking get that I don't want to do that. It's not some carthatic thing I can get out my system, I don't forgive this man and I don't want to see him, unless he's gonna be on fire or something. I haven't seen him for over a decade, and I've come very far in my recovery from that abuse - last time I saw him I had barely acknowledged that it even happened and that what did happen was my own fault anyway.
AIBU to give a firm no to the wedding now? My brother said he will 'seriously fall out with me' if I don't go
