I think you are doing the right thing...following your head and what you feel may be best for your and your kids. It's not easy. He thinks he is ready to come home, get a job and get on with your life together, but, just as I feel is going on in my life right now, it's all about him. His wants, his readiness. If you feel you are ready and he is willing to come in on your terms right now, great. Good luck, I hope you two can agree on terms, whether it's living in the same house or apart for a while.
