I get that you don't want to acknowledge how he's been hurting you because of all the love he use to share with you. But what is it going to take for you to let him go. Tell me if he was treating you exactly how he is right now, when y'all first meet would you have dated him? Would you have seen him as a fit father?
I don't recommend this but if you signed the papers under duress it would make it possible to have them dismissed. Though mystik you have the choice on what to do. You need to think of your well being and your S.
