PLEZ HELP...how do you know when a guy loses interest???****BEST ANSWER REWARDED*******?

IM KINDA IN THE SAME SITUATION THAT YOU IN....I THINK YOU CAN TELL WHEN A GUY LOSES INTEREST IN YOU IF HE'S IGNORING YOU OR NOT PAYING NO KIND OF ATTENTION TO YOU. BUT IF HE'S REALLY NOT TALKING TO YOU SHOULD GO TALK TO HIM AND ASK HIM WHY HE NOT TALKING TO YOU...BUT HIS ANSWER MIGHT NOT BE THE TRUTH SO YOU GOTTA BE CAREFUL...
