It's obvious he's trying to control the situation AND control you. He feels like you've "trapped" him or "won't let him go". BS!
My W said the same thing to me. I told her she has the choice to do whatever she wants, I have no "control" over her. Same as yourself. Just because you don't agree with what your H wants, suddenly you're controlling. It's typical WAS talk. They continue to heap blame on the LBS because they can't deal with their issues themselves and refuse to get help.
That's where your boundaries come in to play. You should not have let him kiss you on the lips when he left. You've got your dignity too. Let him do the work if he wants but he can't "make" you sign just like that.
Read over your post again. "He wants me to really look over the papers and sign them." What's with the "he wants". Do what you need to do.
Get representation on your own if possible so you don't owe him anything. You don't need a buyout. If he thinks your M is a simple commodity that can be bought, then he needs to think again.
Learn the rules and protect yourself first and foremost. Stop engaging with him. You have the papers, fine. But he can't make you sign them right then and there. If he calls you to see if you've signed, tell him you have the papers and are looking them over. then end it. If he keeps calling you asking if you've signed them, tell him that you told him what you were doing and that he doesn't have to keep checking up on you. If he keeps calling after that, just don't answer his calls. You're going to find out that his anxiousness is going to turn into an obsession with him then demanding you to sign or accusing you of things.
Stay in control. You'll see your H change from a grown man into a teenage boy right before your very eyes. Don't let him pull you on his emotional rollercoaster.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
