^ Now this is wrong that you wont trust any Pakistani gal again. I have yet to see any better gal then a Paki or even some indians gals are very nice.
Anyway the thing is that one should keep least, and i mean LEAST, expectations from others. The least you expect, the better chances you have to survive in this world.
Believe me no one cares, you live or die. you are hurt or in intense pain. Some people know the art to move on with life. The losers are those who want to stick to their past and either keep repenting on what they did in past or keep asking questions which have no answers. hence waste their most precious time.
Move on, she belongs to someone else now. She is not going to answer for any of ur questions. May be you can think of good times you spent together. May be she really had some majboori that she couldnot share with you. You never know. So let it go, bearing the good memories in mind but accept the reality with open heart that she was not for you and already gone to the right person, the one who was chosen for. There must be something better waiting for you. AS they say When God takes something from your grasp, He's not punishing you, but merely opening your hands to receive something better :)
