BobbyFresh said it first, call the whole thing off. I will tell you what happened with me. I got engaged to a girl that was 18 that had self conscious issues. She didnt like porn, didnt want me hanging out with friends that were girls, tried to control me, would manipulate any situation to her advantage, would play all the stupid little games that young girls do. She was a bitch. I ignored all the signs and still got married. We didnt last two years, hell we were in marriage counseling before 1 year. Save yourself the time, money, drama and call it off. She wont change.
