Is my boyfriend sleeping with his roommate?

My boyfriend and a girl he knew since they were two have a two bedroom apartment. I don't think there is anything between the two of them and without questioning him he stated that their nothing between them. But other people think I am being naive. We are in a long distance relationship and usually take turns seeing each other every other weekend. I stayed at his apartment in his room and neither of the times have I met his roommate. If she was home she was in her room except for one night when I was in his room and she came over with her male and female friend but I was going to bed. Isn't it weird we did not meet? Is he sleeping with her? Or lying about our relationship?

I do kind of think he may be sleeping with someone while I'm away, because guys always think about sex but I really don't feel as if it's the roommate. Is that stupid of me?

It isn't a given that because you did not meet her he is sleeping with her. It may just be that she has a totally separate life. I have had male roommates in the past and did not sleep with them, in fact I rarely saw them. Is there a reason for you not to trust him/ Sounds like your friends are talking about things they have no idea about. If your boyfriend is normally honest, why doubt him now?

Your long distance relationship probably doesn't help matters. Honestly, I think he's having his cake and eating it too. Sorry if that sounds harsh, but you've been to his place and haven't met his roommate, that sounds strange to me. What straight guy has a female roommate that he's not interested in on some level?

yeah 2 rounds in one day, he's deff.takin advantage of that. You're screwed...literally.

Oh my LORD i agree with Justin! your boyfriend is sleeping with another female come on now i know you have sense then this
