I recently got into a friends with benefits relationship with a guy friend who has a girlfriend that lives with him. He doesn't want to end that relationship because of his 13 year old child that lives with him. He says once his child is 15, he will have no problem ending the relationship. He and I went out of town one night (she doesn't know about me), we text every day, and he calls me on his way to work and after work on his way home. He and I work together so we also talk during breaks and throughout the day at work. Tonight he told me he would feel as if he were cheating on me if he were to have sex with his girlfriend. Any opinions on what's going through his mind? Is he possibly wanting more but because of his situation he is confused?
