i have a master but i think what u should do is juz forget her.... dun cos of a tree let go of the whole forest...i also tio b4... my "ex-gf" tio by 1 guy and was confirmed by few masters that the guy used "kong tao" ... but i did not do it back as there will be more karma.... so leaving her is not a bad choice either... i think u should cheer up and do what u want now.... life still goes on... stay cheerful and happi always and everday is a new start... cheers...
