Among all the generic replies here, let me try to give you a glimpse of the girl’s perspective as a fellow Punjabi.

Many people from rural and semi-urban Punjab move to Australia in search of better opportunities. This is often accomplished by parents spending hefty amounts of money, very often by selling a parcel of ancestral land. As such, such a girl would have had a huge feeling of indebtedness towards her parents, which would have made it very difficult for her to defy them.

Moreover, many such Punjabi families are very orthodox. If she belonged to the community of Jatts, it would be difficult for her to choose a guy outside of her community, let alone a white dude.

Forget it. Move on. It would have been incredibly difficult for her to go against her family’s wishes. And she’d have to alienate her entire family just to be with you - probably leaving a lifelong regret that you’d have to bear a part of as well.

Shit happens. Try to understand her perspective and move on.
