Uhhhh....Sooo tell me what you think..?

Okay so there is this guy that I'm totally crushing on super sweet and sexy as hell, but the problem is he lives in another state and the only reason he ever talked to me is because he thought I was pretty when he saw me while I was in his state and he knows some of my family that is there. On top of that he is moving even farther. I know I should totally avoid the whole situation but I can't stop thinking about him. I don't ever text him he always text me and sometimes I don't even text him back, we were supposed to meet once but it didn't work out and I ended going home obviously still with this fabulous mystery boy. I know what he looks like and we are friends on facebook, but ... is it crazy for me to be so nuts over a boy I have never seen in person or talked to?
