I met this guy last weekend and we hungout one night.?

we live a hour apart from each other, and he works were i live. So he said he would be back a week later and call me when he got into town.He seemed sincere, but me being a female i'm wondering why he has to wait a week to call if he's interested? He's a virgo (if this means anything)....so i texed him once and he never texed back..am i a idiot or just over excited..we had great chemistry and he was really sincere...he did say he was single...
