Guys why do you disappear and come back to a girl? why?

OK so why would a guy say talk to you text you pursue you, and say you hook up ( no sex, no oral) just make out, dry hump w/e. than he gets the idea nothing further. He disappears, become a bit distant if I text so I stop 2 texts max if he still has same attitude I back off. Than I hear from him... Show More
