Sorry to hear of your misfortune. I sysmpathize with you, and hope for the best. If she was willing to sacrifice the 5.5 for a new guy, then maybe it was best, anyway> Either way.. I can't stand the people that say "I wasted 3 years of my life on you" or whatever, after they break up. It wasn't a waste... if it were, then why stay 3 years??? It was good, then... and should still be considered "good", when remembering it. Anyway... enjoy the memories, and who knows... if she is the one, maybe things will be worked out..
Best of luck..
