Aibu to be really annoyed with him?

[mum2benicole]

Ok so my partners had a meal with old friends planned for just over a week. Tonight night table booked for 8pm, ironed his clothes while he was in the shower I even played for his hair cut and gave him £40. We have two kids one is almost 3 the other 14 months and they aren't easy to get to bed.
He said he would help me get them to bed and settled before he went out which is normal done by 7.30 but it came to 6pm and he said I'm of bye and took off. I just managed to get both kids down and sorted myself but I'm so annoyed he just upped and left me! He also said he wouldn't be back late before 9.30 yet still no sign and not a single text.
He would have called me 20 times if that was me out so I'm in a right mood.
Aibu?

Why did you 'pay for his haircut' and give him money....odd

It's not exactly late is it?

I guess that means OP was looking for opinions that would back up her own and isn't too thrilled with what people actually think. She says they have no extended family etc.so maybe there's a lack of perspective on how most people care for a family and build for the future - in my case it would be my Mum sitting me down and giving me a good talking-to and telling me to get my shit together. I wouldn't want to hear it but I'd know she had my best interests at heart.
OP's young and she has her whole life ahead of her as well as two healthy children. I hope she does think about what people here have said because she could be getting so much more out of life than sitting around stewing over why a partner wasn't home at 9.30 or having him call her endlessly when she is trying to do the grocery shop because he can't bath his kids on his own.
