I can tell from my mamu's experience that this is not true at all. I know for a fact he was pressurized into saying yes to his wife on every occasion. After the Nikkah he made it very clear to his dad that he didn't like his spouse, he felt something was seriously wrong with her and that he does not feel comfortable and he does not want to go through with it. However my nana was like "Shareef people and pathans once they have given their word do not go back on it", he tried lobbying with his siblings but none of them wanted to get involved in a confrontational situation with my nana. Plus my mamu also have severe self confidence issues and doesn't really take steps, decisions unless he gets solid backing from everyone.
Even during the marriage which lasted for 18 years, on many occasions he wanted to leave and divorce her but my nana never allowed him to do so and his siblings stayed out of it and mostly just kept telling him "Stay together, make it work together, do it for the sake of the kids".
The moment my nana developed severe Alzheimers and lost his cognitive functions and memory, my mamu became much more bolder, also his spouses behavior became much more out of control where she assaulted my khala and openly started abusing her in laws and could no longer hide the sczhiphrenic thoughts in her head "I saw you using my kids tooth brush in the toilet", "You guys are conspiring to hire a hitman to assasinate me", "You guys put poison in my milk", "You guys are using black magic against me", "You guys feel the reason why i come late from work is because i am having an affair with someone".
Eventually even the siblings had had enough of her antics and had no reason to fear how their father would react anymore and finally told my mamu "We will support any decision you make" at the age of 50 with an 18 year old son and 15 year old daughter. I personally witnessed my own mother who normally stays out of these things egg my mamu on in 2012 "Why don't you leave her?"
But every X, Y, Z including my mamu's siblings whenever he feels angry, depressed, let down by the fact they never stood by him or supported him when his father was alive and well, tell him "It is entirely your fault", "No one else is to blame", "You could have stood up to your father and siblings and done what you wanted", "You were a grown man, adult with a mind of your own, did someone put a gun to your head to force you to live with her and not disobey your parents and siblings?"
Seeing how everyone blames him and mocks him frustrates the hell out of me to this day.
