I just can't find any kind of document on Arkansas law that I can give to him stating I don't have to get his permission to come back in the house after going to get a gallon of milk. Does that make sense, I feel like I'm rambling now? I will try to find a pro-bono lawyer Monday and hopefully get some answers.
Since you obviously can't figure this out on your own, especially the part about what you signed loan wise, etc, get yourself to an attorney and get some good local advice. If you are in LR, go to a woman's shelter to see if they can offer some assistance or guidance. It is beyond me why you had to do anything with a loan if you have any interest in the house.
My advice stands, grow a backbone and stand up to the jerk. Get a set of keys so that you are not a prisoner in the house. If he tries to throw you out or gets abusive, call the cops. Unless you start being proactive, he will keep you right where you are today until you finally wimp out completely and move out, which is what he wants you to do. No muss, no fuss.
All I'm really trying to figure out is what rights I have to the house while I get my life back together since I have $0.
Then figure out a way to get some legal advice, get the loan papers, house papers, whatever and have them reviewed. Borrow money from your sister or whoever if you have to pay for the advice.
