I honestly believe that you should stay away from there, for it hurts me to my heart when I hear of women that have been violated. He may constantly be thinking of taking forceful advantage of you, until one day he decides to do it.
I have noticed that a wife usually stands beside her husband even if he is wrong, for its hard for them to believe such bad things about their husbands (they are in denial).
I support what Southern belle says about telling your parents. Also be prepared for you aunt not to believe it, if your parents tell her.
Please dont let yourself be another victim of abuse.
