Does he want to work with me or is he just stringing me along , too?

This guy was playing me...till I caught on and earned his respect. He trusted me so much in fact he gave me his pwords to his emails and has ME run a dating site for him to find lots of other girls to to whatever he wanted with. Only deal was I wanted to be in on it. And I mostly was. He called me from these girls phones and told them all about me being his best friend and everything. Well for Christmas he wanted to get me a necklace he showed me . ALL his idea. I did him favor and got some stuff for him, he took it and promised to pay me back and give me my gift on christmas (he also gave me his ID to hold as collateral). Well christmas came and went with no word. I called a couple times but his roommate says' I haven't see him'. But I know he's on line macking on ladies cuz I still have all his pwords so...he's not dead or in jail or nothing. Just avoiding me. So what do I do now? And WHY bring up getting me a gift just to skip out on me. Maybe he's back into drugs. Then I won't take it so personal .
