Aibu?

Hello everyone.
So me and DP have been together 6 years with two DC. His uncle is having a 50th birthday tonight and he is saying he wants to go. Bearing in mind he hasn't seen said uncle in over 10 years nor the children (his cousins) so I really can't see why he wants to go since he will know hardly anyone there apart from a couple of cousins and his auntie and uncle. He is also very aware of the fact a couple of his ex girlfriends will be there as they are very close friends with his cousins which seems to me he purposely wants to go to catch up with them.
He hasn't had the best track record in the past (never physically cheated but emotionally did with a work friend when I was pregnant which took me a long time to get over).
I however, can't attend as have to stay at home with the children as he refuses a babysitter when I can do it?! Don't get me wrong I would feel uncomfortable going as I won't know anyone but an invite would be lovely. He hasn't been formally invited, just a brief "family and friends welcome".
AIBU to think he shouldn't go? Or should I just stop overthinking so much and let him get on with it?!

he refuses a babysitter

Um, think this is more worrying than the issue you posted about frankly

Uhhh how does he unilaterally ‘refuse’ a babysitter?

It's because family members aren't available and he wouldn't want to pay for someone. Apparently.

Just for him saying he "refuses a baby sitter" he'd be told to go and not come back!

But you want to pay for someone, don't you?

Tell him you'll pay for a sitter yourself. I doubt he'll still want to go. Prick.

Yes I would pay for someone, but it's getting someone now at such short notice. He only told me 2 days ago it's tonight and he was going so hasn't left long to get things sorted and I'd have no chance to go now as finding a sitter the same day is difficult.

What happened if you just 'popped in' with the children?

Book a babysitter and don't tell him till they arrive. Then you can go together and watch him squirm in front of his ex gf's!

If I lived near you I would come and babysit for free

He doesn’t get to make this decisions alone, you do not have to stand for that. Urgh he just sounds like a twat.

Your kids are his uncle's family. Are they not 'welcome' as well? A 50th in my or DPs family would have kids there. Is that not normal?

If he won't get a babysitter then I would rock up with the kids if he's insisting on going. I expect his family at the party would like to see them anyway.

If he refuses a babysitter take the kids. And say that is what will happen every time he decides he is going out but you have to stay home as he won't get a babysitter.

Why would he want to go to a family party without you?

Stand up to him and take the children.
