Am I leading him on?

So I met this guy recently and I immediately liked him and we made out and hung out all day last week. But this week he was telling all of his friends that I'm the best girl he's ever been with and how he really likes me and all of his fiends are asking me if we're dating now and it's a total turn off. I've also learned more about him this week and now I don't want to really be with him at all and I think I want to end it. If I do end it did I lead him on am I in the wrong or am I acting like a bitch? It's just so much drama has been created out of it and I don't know what to do.
