I havent seen any difference between lover and wife's love till now except in case of love failure and married a girl due to some reasons..however in real life i saw every marriaged couple blaming each other even if they are lovers or not lovers before marriage.
In 2007, the Rajasthan High Court ruled that a man can’t sue his adulterous wife – but he can sue her lover for violating his ‘proprietary rights’ over his wife
Some have asked why one does not marry lover and if does not do son, this is not love.
Let me explain. It is not always possible to marry lover. Love recognizes no age, caste, status barrier. It may happen that a sixteen year old lad/ girl loves two year senior. But by the time the lover is fully educated and employed, the lover is already married to someone else. Also, the lovers may be separated by parents' transfer to another station. True love is when you are teenager. Teenage love is the first love and is unforgettable. But this will seldom turn in marriage. Then you have to adjust with another boy/ girl to whom you are married.
If its lovers people dont take anything careless, because they know if they take it careless it will end up in breaking up, its not the same with wifes.
