Marriage is for Life. Take a view objectively, r ur parents the reason for the clashes between you both ??
Whats the harm in taking a seperate house in same building or nearby parents place say for 6 months and see how things progress , if that is going to save ur marriage. U continue staying in touch with ur parents and care for them and ur wife should have no business to interfere in the same arrangement.
No you should not dump ur parents for wife, but u can work out some middle way if possible, to save the marriage & if you think that ur wife otherwise is good.
If u do not agree to her terms she will claim maintenance and seperate accomodation from you. Also may file 498a or divorce based on how shes influenced by her lawyer. You can then defend case on merits but will end up spending 3-6yrs in court if things turn nasty.
