He is either not interested and didnt want to hurt your feelings or give him time as he might not want to rush things. Or he is busy and a lot of guys just don't like to yammer on the phone.
Why Does A Guy Say He'll Call You And Never Does?
He could be playing hard to get, tring to make you hopelessly anxious on whether he will call you or not... Or.... Hes just not that into you :)
He just a guy who is not being serious.
Maybe he's just trying to do other things.And I THINK YOU KNOW WHAT I MEAN BY OTHER THINGS.So it helps if your more popular than he is,that way theres less of a chance for him to let go of you.
Trying to be nice but ending up as a jerk... =C
