<human>: Can you give me a shortened version of the text?

I recently went through a pretty traumatic heart break, almost a year ago, which is unimportant except that it is what has made me avoid getting involved with anyone that I actually like since then. I am having a rough time getting back in the proverbial saddle. 

I have known this guy for years now, as he is tightly ingrained in a friend group of mine. Our respective best friends are in a relationship. He has always had a thing for me, and has made no secret of it. Last week we slept together, and it was awesome. Not only is he great in bed, but every non-sexual interaction was really satisfying. What I am trying to say, is that I LIKE HIM, like him. 

I am nervous. Really really nervous, which I know is normal, but I have an obsessive personality and I might need some talking down. I know what everyone is going to say, that he's already indicated his interest and what do I have to worry about.

I guess I am worried because he is younger and I know what I was like at 23, I fucked anything that moved, so I don't expect him to be any different. I also know he is involved with someone(s) else, not exclusively, and dating more than one person at a time is not something I am interested in right now. I think that it would hurt my feelings if I was seeing someone and they were seeing other people at the same time. That is how dating is, I know, but it still suuuucks. Also, I would like to think that of all the people that could be in this situation, if things were to not work out, we would both be pretty cool about it.

What I am asking is, do I continue to get to know him better, or do I protect my obsessive, somewhat bruised psyche and back off?
<bot>: I like a guy, he likes me back, but complications like age difference, dating style, and mutual friends are giving me doubts about trying.
