This is messed up but I have been conversing with a chick from work, who has a fiance, for the past 3 months. He went out of town and we went out and had sex in her apartment. It isn't just about the sex, I really enjoy her company and could see myself with her...The guy beats her, steals from her and, according to her, never wants to have sex. We have hooked up a few more times since then and she constantly tells me that she's going to leave him but I feel as though she's just stringing me along. Any advice?
