There's this guy.. what do you think??

a few weeks ago we were at a party together, and he offered to take me home, i was drinking so i couldn't drive. when we got back to my place we sat in his car talking for almost an hour and then ended up going to Denny's where we sat and talked for 3 and half more hours.. when he took me home again, we sat in his car talking for 30 more minutes, we exchanged number and have texted back and forth a few times.. Do you think hes into to me? would he have asked me out again by now or am I over thinking things? oh btw.. hes been out of town for work for the last few weeks so we haven't had the chance to hang out again.. if there is even the chance.
