Gosh Candace, I'm reading all this now, and all I can think is, change the locks, and don't look back. Seriously. It sounds like he's just going to drag you down with him where ever he is going to. And "forgetting" to sign the check... sure. Whatever on that one. I'm not buying it.
Get any money back that you can, get the locks changed, sell what remains, and don't look back. You deserve much more than what he has to offer you.
Hugs... Jenn
