I dated this guy in college for about 6 months which was about 4 or 5 years ago but there was definitely something special about our relationship and every year he calls me randomly and sometimes we hang out once a year just as friends because we live in the same area.
He called me last week and we chatted for about an hour or two reminiscing about college and stuff and this past week he has called me almost every night between 12 and 3 am but I'm never awake to answer it because I work and stuff.
Why is he doing this now? Whenever I see his missed call I try to call him the next day but he barely ever responds and he's not drunk when he calls me and he wasn't drunk when we talked last week.
Why would he call me then not respond when I try to figure out why he called me?
