What does he want from me?!?

From my experience, he's playing you. Which isn't necessarily a bad thing. So basically this whole not communicate with you for a few days thing is a move to make you desperate and think of him which is basically working since you're asking this question on the internet. Now, whoever you're dating is either a player or someone who really likes you but intends to win you over through some creative (some might say unethical) relationship move. Either way whatever the hell he's doing, it's working because you're thinking of him. Anyways, my theory can be wrong so don't take it to hurt. Sometimes people are busy, and aren't used to the level of commitment that you would like so give him some time. If you think he's doing some "creative moves", talk to him about it. It's going to end up that he's a player, he's insecure about the relationship and feels the need to do this or that he's just busy. Either just talk to him about things, let him open up to you and all will be revealed.
