He really does!
@mummy917 you are clearly a wonderful mum. Try not to beat yourself up about not finding the perfect solution. Unfortunately, you can’t change the type of parent (or person) he is. I would do what your gut, your heart, your kids are telling you is best, irrespective of whether that feels like it’s ‘giving him what he wants’. There is no point cutting your nose off to spite your face, just because what you want dovetails with what he wants. Keeping him at arms length, expecting nothing, being beholden to him for nothing seem to be what’s best for you and your mental health -and it’s obvious to everyone that you are the best person to be making decisions about what’s best for the kids, and to spend most time with the kids (as far as you can comfortably manage, and in a way that enables you to work and obviously allows the kids to maintain their relationship with him for as long as they want to). Do what makes life easiest for you and the kids now.
Longer term, I really would be thinking about whether you can find a job that allows you to access childcare more easily, because I think it’s increasingly clear that 50/50 isn’t sustainable - or in the kids’ best interests. Is there anyway you could get a role at a GP surgery, or as a school nurse, or outpatient clinic - anything that does office-type hours? Or, is there a uni/college nearby where you might be able to recruit a student (PGCE, Early Years, Childcare, Children’s nurse) who could come to your house in the morning to do the school run, then collect the kids from school and do tea and bed time? If any of this is possible, I’d be seriously considering asking for an EOW agreement, where be collects from school every other Friday and drops them back with you on a Sunday evening (or back at school on Monday if he can be trusted to launder their uniform, do homework etc.) if he pushes back, he could have one night in the week too, if you think that is in the children’s interests. He’s a cock. Obviously, I wouldn’t be sharing any of this with him yet, but I would be seriously thinking about it.
