Not the arsehole He didn’t talk to you, you have plans and that’s that If he did discuss this with you and you had nothing on I’d say meh do it but otherwise nah! It’s not your responsibility to look after kids that aren’t yours with no communication regarding it He can text his ex and say sorry due to my new job and shifts I won’t be able to get the boys sorry for the misunderstanding I can take them out on X day!
No he is the arsehole. He’s been inconsiderate and careless and he can’t expect that to be ok. Put your foot down and stick to your guns otherwise you could run the risk of him taking the mick in the future x
Nope this is on him. Don’t open your mouth and commit to things you have no intention upholding. It’s not your responsibility to clear up after him.
You've absolutely done nothing wrong. Theres no point in having his kids, if he's hardly gonna see them, due to working. He's in the wrong for saying he'll have them and not discussing it with you first. That is absolutely wrong. You should be the first one he discusses it with
It’s on him to make plans not you, he’s asked you and you’ve said no. This is still his problem, not yours. I hate it when men treat us like their free childcare!
