Hello lostparadise: I see this is your first post here on PC. So... welcome to PsychCentral.

I'm sorry I don't know if there is much I can offer with regard to the situation you describe. I see you list yourself as being in Mumbai. So I presume your culture is different than what I would be familiar with. I suppose the situation you describe could occur here in the U.S. where I live. But I think it would be unusual that a father would be able to prevent a married woman from returning to her family. However it is also unclear as to whether your father-in-law is actually preventing your wife from returning home or if she is choosing to stay away.

Anyway... you asked for help with regard to how to cope. So here are links to 5 articles, from PsychCentral's archives, on the subject of how to heal from heartbreak. They're intended for people whose relationships have ended. But perhaps some of the suggestions in them can be of some help to you too. Also included are links to 3 articles on healing relationships plus 3 on what to do when you feel lost:
