Two things, we must understand. In Hindu Marriage Act and Special Marriage Act, the grounds for seeking divorce have been well laid down. In that incompatiability is not a ground. similarly, getting annoyed with husband's sister or neglecting the husband's brother are not grounds. Similarly, feel proud and give importance to professional career is not a gound for divorce. Even having no cardial relationship (even though this ground has not been mentioned but in several querries this point raises), with the in-laws is not a ground. Even then, all these activities of the wife, in the perception of the husband, amount to "cruelty", but in law that is not cruelty.
Incompatiability and irretrvable break down of marriage are not grounds. Indian boy suffers from two vices - He feels that if he is showering love towards his wife it amounts to disrespect and non-affection towards his parents and especially mother. He feels so much guilty. It is not so. Similarly, he expects, that after marriage, the total influence of his inlaws and their family on his wife should be vanished by a magic wand and she should surrender herself totally and demands that she shall not even recollect her sweet memories with her parents and brothers and sisters.
When husband tries to understand the 21st century woman, he will be happy. If he tries to live in 21st century and expect his wife of 18th century, these problems will crop up.
