after breakup advice.

First of all i've never been a huge fan of hookups, ironically thats where i met my ex.We broke up about two weeks ago, my best guess is that he emotionally checked out about a month prior, but i didn't.i still have strong feelings for him and he works at the university i attend and im seeing him and his car everywhere.any tips on how to deal with it because im trying to throw myself into school and work but i find myself checking his facebook ect...I know that now its over I'll eventually be happier because the relationship wasn't making me happy anymore (he wasn't trying), but its still just weird.
