Oh hon, I feel ya on this. My H is being very ugly as far as finances are concerned. My sitch is very different from yours, as I am a SAHM. He just can't seem to understand that it's really not all about him. He left me. He's going to have to help me to get on my feet financially. I worry that the financial arguments will be what will drive us further apart.
What your W is trying to do is emotional blackmail. I wouldn't sign anything unless you are comfortable with it. You have to look out for your own future here. Maybe in the future, have your W keep finance talks to email - makes it a little more impersonal. That's what I have had to do, and it helped calm things down a bit. Plus, it gives you the opportunity to focus on better things when you see her. Takes the focus off the negative crap that is money.
