I agree with everyone else here, you need to start respecting your wife. Go to Pakistan and solve the problem.
I think you need to be a man and start taking your own decisions, instead of running to your mothers lap and hiding like a boy. Im sorry but you sound like my ex husband, he needed to grow a spine as well, but he kept hiding behind his parents like a 5 yr old.
If you want to save your family then you have to take actions instead of asking your wife to take action.
And like others here have said, there must have been something serious that your wife has left and doesnt want to go back. If you could accept and share your mistakes and problems here, we would be able to help further.
