I do not think we know the entire situation. It also sounds like you're hearing this as a third person and not someone who is close enough to the girl to know the complete story.

My suggestion would have been marriage counseling but a lot of times marriage counselors in the US (is that where you are?) dont know how to advise in arranged marriages. I would suggest the local Imam and then if that doesnt work, an elder from the outside. Not someone from either one of the families as they will be biased.

One more thing...if this guy is so majboor and abused by his wife...how did he manage to put her on a plane and send her back to Pakistan with the message that someone better fix his wife otherwise no need to send her back? It doesnt make any sense to me.

I smell something fishy here.
