Search Results: he gets very into it when were kissing

I have a friends with benefits and although I can I haven't really slept with anyone else, more so because I work 50 hours a week but also because he is really good. Anyway, he's been suspicious lately ever since I started working again. He will make jokes that are obviously a little more than jokes for example I am sick and he says "maybe you should stop kissing so many men at your work". And at first I just laughed but all of his jokes are about the same thing, me sleeping or being with someone else. I'm starting to get the feeling he is trying to make me admit to sleeping with someone else without being direct because we aren't exclusive. I think he feels guilty because he has been talking to another girl and he wants me to have been doing the same thing so he doesn't feel as bad maybe? He also tried to hide the fact that he was trying to get with her from me but it was painfully obvious that he was and his friends were talking about it to me, so I asked him if he slept with her because I don't want any STDs, But then he says she's not into him even though to me she looked very into him. And that same night asked me to stay so he could lay with me instead of just leaving after sex. He's really sending me mixed signals and it's kind of been messing with my head. Was he feeling guilty, jealous or playing mind games?
