I'm confused, what should i do?

I've known this guy for a couple months now and it's weird. I met him through a friend and I know that he likes me. We met in person and there was just akwardness and still continues to be like that. But when we text, it can go on forever. I started to like him too but then i realized that it was just out of desperation (i'm not saying he isn't good). I've never dated before and i'm not nervous to start one. But i'm just scared becuase i know he wants and i'm not gonna give myself up until i'm married. He told me himself that he wants it, well he didn't literatly. He's a good guy and everything but my friend tells me he just hangs in his room all day and is constantly on his laptop doing whatever he does. Then he told me about his ex and how all realtionships end up with the girl messing with his heart. I admit i do tease him and do kinda wanna be with him but then i got family problems, i'm in the time of deciding what i'm gonna do after college, and my friend tells me he's not good and does whatever he wants. The other day he told me he wanted to give me his love and we were also messing around, so i don't know if he was serious or not. What do I do? Any advice would be helpful.
