I'm telling you, you still have thru thru the weekedn to go down and do it in person,only way to save it. Otherwise, you need to wait 1-2 months and hope she misses you so terribly that she wants you back.
Just go down there man. What is stopping you, unless you really don't care for her as much as you indicate here.
Otherwise, buy the local some jewelry (24 karat gold for all asains, not htat 18 karat crap) and tell her "Baby, it was always you" and take her away for the weekend, somplace nice.
Don't just sit with your dick in your hands, take charge of the situation.
I have faith in you.
Gotta go catch a train to a plane to Cali.
