He either wants to play the field or he's lazy. Stop what you are doing! This guy needs to get off his butt! If he really cares for you then he'll make the extra effort to call you and make dates. If not, then consider yourself lucky. By keeping in contact with him you look deperate and needy and some guys will take advantage of this. Start going out with at least your girlfriends. Don't phone him, email him or IM him. I bet within a week he'll be contacting you, but you may surprise yourself and realize you don't need him after all.
