boy trouble

So my friend with benefits likes this girl and is trying to get her to go to the college that he wants to go to. There was a dance the other night and he was going to go with her but he didn't. I asked him why and he say he just didn't want to and I asked him if he was alright and said I don't know. The last time we had sex was the next night and somehow it was different. More intimate and I'm not sure what to think of it all.
