My boyfriend (he's 19) lives with his step mother and father, the problem is that he use to have a crush on her, although his dad is in his late 30's,she's really young 23 yrs old. When we use to be friends, our mutual friends would joke about "when was he going to bang her" and etc. He usually ignored them and told them to shut up because we were secretly dating (this was about four years ago in HS) He had told me that he had found nude pictures one time and kept them and jerked off to them, at the time this didn't really make me upset because it was in his past and a horny teenage boy will jerk off to pretty much anything, we were also in a long distance relationship and he wasn't living wit his dad so I wasn't concerned. Now this past year he finally moved back and is now living with them. I wouldn't have such a problem with it but she dresses like a (Sorry to use this word but) a tramp. She's always wearing booty shorts, crop tops, see thru shirts, and I wouldn't care if she were to wear them out and about but she wears them around the house while he's there. Call me crazy but if I had a step son I would make damn sure I was covered up. I hate it so much, and he doesn't understand when I tell him that I get mad when I think about it, he tells me that he doesn't see her that way anymore, but come on, you can't just stop seeing someone attractive who you've found attractive and who's dressing like that. It hurts me at times to think that he can be fantasying about her, I feel like whenever he leaves his door open in his room he does it on purpose to see her. Are my feelings wrong, am I wrong to feel this way? Idk what to do? I just feel stupid for feeling this way.
