Don't even think about living with your in-laws. Really, really, really, really, really bad idea. If YOU want to get on with YOUR life, don't tie it to HER family. And make no mistakes, they will be HER family. Really, really, really bad idea.
And, playing house with the kids while she is at work is also a bad idea. You have your space. You see your kids in your space. She has her space. She sees her kids in her space.
You may not see it, but you are still in fairytale land yourself about D and life after D. The goal here is to separate financially and emotionally as cleanly and COMPLETELY as possible.
Of course, if you still want your life to be about your XW two or three years from now, and have your energy sucked out of you and morale beaten down on a weekly basis, then entangle your life with her parents and plan to share space in which she conducts her personal life.
