So you don't care about a contract? Probably means your word isn't worth much if you would fight not to do what you agreed to do. I hope you pay to have your trailer remodeled and the contractor takes your money and runs. Then I guarantee we will hear you screaming about the signed contract you had with him. I sure do hope you are not in business. You ask if you should go back in? No, your time is up and fulfilled. Hers wasn't. Very simple.
