My boyfriend and I mutually broke up a few months ago. At that same time, his best friend and his girlfriend broke up. And I find myself falling very quickly for my ex's best friend. I have always thought he was attractive, and we get along great. We have so much fun together. My ex has also told me (by complete coincidence) that he thinks me and his friend would make a great couple.

This all started when we went on a vacation with our friends. We both agreed we should share a room, since there was a limited number of beds. We ended up sharing the bed, giving each other backrubs, with our shirts off. This was strangely out of character for him. I wasn't sure what to make of it, but it just ended there.

Since then we have talked about being friends w/ benefits and whatnot, and we have fooled around. We ended up doing pretty much everything except sex. It was just once. (We haven't kissed, though.) And we've done the backrubs thing again, except much more "friendly". And all of this we are keeping from our friends.

We also have hung out a lot more and talked about some pretty personal things. He has told me things he hasn't told anyone else. Our amount of communication has practically tripled since that vacation.

My feelings for him have been increasing rapidly, and all I want is to be in a relationship with him. The problem is that he is still hung up on his ex whether he admits it or not. And he told me about a month ago that he isn't looking for a relationship.

I can't decide if I should back up entirely, or if I should stay being close friends w/ him (benefits and all) and take it slow. I'm hoping that we will end up in a relationship in the next several months. I don't want to rush anything, but I'm afraid of letting myself be really into him, only to find out that he doesn't want me at all.

Everything about our "relationship" shows that he really likes me. It's just that sometimes I think he gets confused and isn't sure what he wants and backs off a little bit.

I need some advice. I can't stop thinking about him, and he's everything I want in a boyfriend. Anyone have any thoughts for me, please?
