What do you guys think about this?
http://www.alovelinksplus.com/advice/double-your-dating-articles/if-she-doesnt-call-back.htmBut the best thing you can do is to just call a woman on the phone 3 or 4 times before you give up! (That is, when a woman gives you her REAL number).
Women expect men to keep trying, so they just don't call back.
Remember, SHE'S THE WOMAN. She's the one who's getting approached by interested guys, and who probably sees you as "just another guy" calling her.
