Some guys are just really dumb with the phone or hate the phone. I'm female and hate talking on the phone. I hate hearing people breathe and talking about nothing and stupid things like what they did that day.I hate the phone so much that I have a prepay and keep it off for days. Guys usually love this about me that I don't call them about nothing.
If you're being clingy with the phone..then that can actually push some guys away.
I actually went through a similar obsessive thing a few months ago. New guy, I wanted to go do something, he never answered the phone. Was driving me crazy because he was always like "if you want to do something, call".. yeah well apparently if he couldn't do anything.. instead of telling me.. He just didn't answer. For days. My favorite was the day he actually answered and said "I noticed you called the other day but I was in an appointment'. Like..ok..so don't call after the appointment. So far it seems over with this goof but yeah.
