Depends a LOT on what he's saying.
If he is talking about you in relationship with the things he enjoys doing with you then it is a good thing. If he talks about you to his buddies about what an insecure, nutcase you are, then it is not a good thing. Don't worry about it. Guys talk more than girls do. We just don't advertise it like you do.
I think it most generaly what he says. I do have 6 brothers and I think for the most ive noticed the more they talk about a girl, they like her. On the flip side though if a guy thinks your easyhe may well share that with his best friends too.
I have a feeling he realy likes you. I would you go on a couple of dates with him, and you will get a good idea if he wants you as a gf.
