Help

I was reading over the laws in my state last night on common law marriages. That is what I had with my boyfriend, but we never tested the validity of it in court by taking it to trial to get a divorce. From what I was reading , he could come back later on and try to get whatever I had. He's so money crazy and materialistic; that he really might comeback and clean me out. I have my own business. I've almost worked my way out of the debt I accumulated to get a legal restraining order against him to protect my life and also to pay for the counseling that I needed after the tramatic time he put me through in 2005. I thought about just sending a piece of paper for him to sign that would be an annullment; that way we wouldn't have to go to court and that would cut ties to each others lives legally.
