Dude...Not trying to be a dick...and not trying to make it worse, but one of the things I learned from Doc Love was....
Always deal in the reality factor...(See things the way they ARE, not the way you WANT them to be)....she's probably seeing someone else...FORGET HER and move on!!!! I know it's easier said than done....BUT...Nothing helps you forget an old flame like a new flame!!!!!!
Give yourself some time to mourn then get back out there...I bet you any amount of money, someone else is involved, there ALWAYS is...
