Who should get in contact, me or him?

I'm so attracted to this guy and he likes me too. Up until now we've been friends..we knew each other a little before he moved to another state. Since then have kept in contact by chat..once a mth or so. Now I have to visit his city for work and he'd love to meet up. Problem is I'm already so into him and can't stop obsessing. He wrote that he's going to fall in love with me. Also said hurry up and come visit. Thing is I don't know him that well..but I do know he's attracted to me & seems like a decent guy. I'm just worried as we don't chat very often. Now its a few wks since we've chatted..usually he contacts me. It's making me insecure but I do know he's really busy now and the last contact (by him) he checked again if I was coming! I could email him but feel much happier if he did this. I think it's much better when the man is more proactive. What do you think?
