There is this person that I know from high school, who just started talking to me. He ask if we can hangout the other night, just to chat. You know to get know one another better. I never really talk to this guy in school. So my feeling were okay I guess nothing wrong with that. This guy is a nice person (so I think because I really don't know him).

So we hangout for we can chat. The whole time that we were chatting, he wanted to kiss me. And I was like no, I'm not like that. He tried more than once to kiss and push him off me. I think that he might like me or something. I do remember in high school that he had some feeling for me, but I never liked him in that way. I still don't like him in that way.

And to make things worse he has a girlfriend. He said his relationship is very complicated. I think that his girlfriend didn't know that he came to see me. I do not want to get in the middle of his relationship.

I don't want to leading him on. I just think that we could be friends but I don't know if that can happen. My question is how do I tell him that?
please help
