My 2 cents on coparenting...the reality is that your h will parent the way he does and quite frankly, it will fall on you primarily. That may evolve over time, however, it will be interesting to see his take. I know that my xh has actually stated a number of times that he moved out *so that he could much more away time from the kids.* That's his decision. His loss.
However, as you know, you will want to have some semblance of a life. I know you have a sitter, and don't be afraid to ask him to take them while he's in town. They ARE his kids too.
You are getting to indifference. Hang in there!
