You live in the same STATE? Why say state and not city? If the dude lives several hours away from you on the other side of the state, chances are nothing's gonna come of it anyway.
But anyway, you sound like how I used to be before I realized cute dudes are a dime a dozen and would text/call them and overanalyze shit and put way too much effort. I'd recommend you do what I learned to do at 18: leave him alone a week. No calls or texts.
If he's busy anyway, he doesn't have time to be getting to know you or date you. And anyway, I've heard that "busy" line many times. It's just what pussies say who are on the fence about if they want you in their life or not, since they don't wanna completely let you go just in case feelings develop or their other guy doesn't pan out, etc. Trust me, no matter how busy a man is, if he wants to go out with you or hang out with you, he'll make time.
If he never hits you up, delete his number and while some people disagree, I personally feel that the best way to get over someone is to get under someone else. I mean, any insanely hot guy I developed feelings for and then we'd part ways...I'd hop on Grindr or Manhunt or Barnes and Noble or what have you...see an amazingly sexy guy who catches my attention and has the barest amount of wit, and I wouldn't even remember the dude I split with. So...you know, go slut it up dude. ;)
