Hi,
Yep men can be thoughtless jerks. While you are thinking about how nice a time you had with him, he's out checking the oil in his car, or wondering if his favorite sports team is going to win. Then along about 2 weeks he remembers, Hey! I got that cute girl's number somewhere and he sets on a course of looking for it. He will contact you if he really was interested and if he wasn't.....well, I'm sorry he's a cad.

Anyway, you can try another e-mail or voicemail but, if he dosen't respond...forget him.

Have a great day.
