Hello Madhoo: Thank you for bringing your concern here to PC.
I see this is your first post. So... welcome to Psych Central.
In reading your post, I noticed you live in India. So I presume there may be cultural issues involved with this situation. And I'm not going to have any useful suggestions with regard to those. However the answer here, to my way of thinking, is to move your wife out of your parents' home. My personal opinion would be that it would be a very special family where a son's wife could live amicably with his parents (& without him being home at least normal hours... after work & on days off.) In fact, even when the son (or daughter) is home I think having a married adult child & his / her wife or husband living with parents can be a challenge.
The fact is you can't change your parents nor can you change your wife. They are the people they are. And trying to imagine there is some way to "fix" this situation, if you could only figure it out, is just putting additional pressure on you because it makes you think you ought to be able to find this fix when, in fact, you can't. Here's a link to an article by our host Dr. John Grohol, Psy.D., from Psych Central's archives, that speaks to this:
You Can Only Change Yourself
So, given the fact you can only change yourself, the question then becomes what can you do beyond moving your wife out of your parents' home. And, from that perspective, at least to my mind, this becomes a matter of personal boundaries on the one hand & coping with worry on the other. So here are links to some articles, also from PC's archives, on these subjects:
