Do yourself a huge favor and dry your tears and get to a lawyer. You need to find out what you can expect and what you're entitled to. Its always better to control a situation than let it control you.
Good luck to you.
You have children that you need to think of first and foremost. Go to a lawyer and find out where you stand. Sometimes when you say, "fine, I'll file then" the WS gets their head out of their ass. If he doesn't then he isn't worth your time anyway.
