My stbx husband and I are as amicable as possible, but it still doesn't prevent the emotions from surfacing. It's good that he has a plan, my only suggestion is to get yourself to an attorney. It doesn't have to be nasty, it will end up painful....there is no way around it. The attorney will look after YOUR interest, and protect you from yourself. I know mine did, and at the time I was sure I didn't need it.

Your children are so young :( ((((hugs)))) Hang in there.
