I think your best bet is to start getting good legal advice. I personally would get a good lawyer if possible. You need to protect yourself right now. Keeping busy, and being strong in this will help with your PMA. Focus on legally protecting yourself and ensuring you get the level of custody you want.

Ignore W's rants and raves. Ignore any ridiculous demands... try to stay calm and logical and make sure you get good legal representation. Talk with a lawyer or your own mediator ASAP.

There is no arriving, ever. It is all a continual becoming.
