I think he meant he felt guilt free when W has the kids, so he doesn't feel bad when he isn't with them, doing things for himself. But I might be wrong here.
trying, H used to tell me his plans, but not anymore, keeps me guessing. Well, not really, I just don't plan anything with him at all, its easier. If there is something we both need to attend (school conference, etc), I post-it his behind and move on with my day.
