I'm sorry to hear this...hopefully you can get some things resolved very soon. Whatever you do, please do not allow your emotions to rule your head. You will need to put your business hat on and stand firm on what you and the boys need to survive. If you aren't sure about something, don't agree w/him or the mediator. Don't sign anything w/o seeking some counsel of your own. It's too hard to get things changed once the divorce is final.

Please take care of yourself.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
