Is my best friend trying to use me as his rebound girl?

Most of my friends are guys, I seem to relate to them better, but last week my best guy friend broke up with his girlfriend of 2 years. When he called me and told me I went over to his house and hung out with him and listened to him the same way I would if one of my girlfriend broke up with their boyfriends. When I was about to leave it was a little late and all of his roommates were getting home and he didn't really want to be around any of them so he asked if he could come chill at my house for a little while. So I let him come over but I was really tired and I feel asleep, but I woke up in the middle of the night to him kissing my neck and trying to finger me. I pretended I was still asleep until he left the next morning. It was awkward because I don't have any feelings for him and I really do just see him as a friend but I'm worried he tried to use me as the rebound girl, which I feel is very disrespectful to our friendship. What should I do?
