A little after I wrote this, he sent me a text and said never to contact him until the day he dies, unless it's about the kids or bills for the kids.
Why would you keep pursuing a man who would continually hurt you like his has? Save/print all this kind of mess that he has emailed you(for a lawyer)and then do what everyone has told you. Let him go, leave him alone, and go forth with a life with your children. Do you really want a man who doesn't want you? Don't you deserve better?
I know a wonderful, wonderful young man who M a divorced mother of three. He gave all his love, time, and energy to that woman and her three children. The kids grew up and adored him as the fantastic step-dad he was. It can happen. You can have a good life but you've got to let go of this before you can.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
