Most Helpful Girl
Are you sure you aren't just a booty call? Have you had sex with him? If you have that might have caused him to become uninterested.
I would ease off communication, let him contact you first and in the mean time hang out with friends and family. One of two things will happen then either:
a) he stops contacting you and if this happens he wasn't worth your time anyways and its better to find out sooner then later.
b) He thinks you might be losing interest or starts to think you aren't desperate so he starts to contact you.
