dude, it sucks that happens.. many young girls are like that. they say Once a cheater, always a cheater... so i hope u dont get back with her even if she begs you. well but these kind of things happen a lot in USA so dont be surprised. u are not alone in this.. u just got to move on and hopefully meet someone else better in future. ofcourse u can always goto nepal and meet soo many chwaaak girls.
