Sexual Attraction

This guy. He has a girlfriend. he is my ex boyfriend. he was sort of a player 'til he found this girl. they made/make a pretty good couple. This guy, He's always wanting to hook up with other girls. What is up with that? Can he not be happy with the girl he has? I mean come on, the girl is pregnant! Apparently she does not want to be with him until the kid is born or something. (Says him.) So anyway, he actually starts talking to me about old times and getting back together, oblivious to the fact that I have a boyfriend, or just not caring about that. So i'm just like WHATHEFUCK, no. Even if he is not with the girl it is kind of messed up that he only wants to get back together for a month. Oh and now he's mad at me for not agreeing to be his play thing for the next month. haha, I was listening to the song In the Next Room by Neon Trees and that's why I titled this "Sexual Attraction" ....even though it sort of makes no sense.......
