To be honest, I don't understand his actions from the get go as well. 'Chasing' you only to quit once it may have started getting close? And how far away from you was he? Being in separate states don't mean much if it's within 100 miles IMHO (unless traffic is a major issue).

Sounds as though you are more of an ego boost to him than anything else. He enjoys having your attention; when he feels you pulling away he reels you back in.
A relationship shouldn't be this hard. You should never have to wonder or doubt where his head and heart are. Find someone who treats you like you deserve to be treated and let him play his little games alone.
