hi
just chill!if she has left u for ur uncle she will surely get out from him sooner than u think. she may take good money from him and then abandon him. trust in god and do the right.
take a vacation , see ur parents more. try to hang out with friends , and things should be ok.time is the best medicine. this is just a passing phase from everyones life.
u shold thank her that she has thought u a lesson or two on having a relationship and having faith in wrong people.
god will help u if u r on the right path
