1. he is not coming back
2. he is see someone else
3. could he still care about me
what were the terms of the break up after two weeks? if nothing was established, then you might want to call him...if he's not coming back, then he would have blocked you by any all means for contact...if he's seeing someone else, he would have cut you out of his social network, i.e. FB...option 3 only happens if you talk to him
If you want to talk to him, call him up. If he doesn't pick up, than you can assume, he's not coming back (yet, if that) and you can assume that there's someone else. All in all, if I was you, I would just end the relationship all together.
