I have a holiday coming up in 2 days with my now-ex and 2 children. Eldest is not his. Youngest is a baby so doesn't know any different. It's not amicable between us, he's nasty hence the reason for the breakup (recent) and I just don't want to be around him. I'm happy to miss out on the holiday, but my dd would be devasted.
Yabu - suck it up for your daughters sake, its only for 4 days
Yanbu - don't go, it's not worth it
