DS has a crap beginning of Jan birthday (sorry anyone else who does!).
I asked him pre Xmas to choose between big cheap park footie party and 3 people to a fancy adventure place (and for complete info- I also texted ExH to say this was the issue and did he have an opinion). He'll be 9 and did park party last year. DS 'couldn't decide' and we've been away for new year so on the 4th I said I'd decide and we invited people for park football. (We live in somewhere warmer than the U.K.!)
Just completed awful divorce from controlling and abusive ExH but have always, at every point kept his access to the children open, honest and amicable. He fights and picks at every.single.thing.
Today he suggests another venue (rented pitch) and earlier (by 1hr) time for the party.
I replied with queries; price (he pays for 10% of our costs despite earning exactly double my salary) and whether it could still have original timing. He replies with an insane rant ending with 'you've ruined his birthday for him. Well done'
So.
AIBU: suck it up, have the earlier time (3-5pm), better pitch and pay.
IANBU: stick to what it is and ignore rants.
Or maybe a third- I'm not being unreasonable, he is, but still go for the better pitch and pay the equivalent of gbp120 for it.
