It is free for any person of the maturity age to choose and find his/her life partner and together make a decision to lead a happy wedded life.
As as far as the selection of the partner is concerned, it is very unfortunate to love or want to marry a person who is already married and when both the husband and wife are alive.
Here the action of Nayanthara is not liked and accepted by the Indian community, where this practice is highly condemnable. She could have loved or married any other smart guy or millionaire of her choice who are not married. But she fell in love with a man who is already married and has a wife and family.
This type of 'love' or wedding may not give a 'happy and peaceful life' for anyone. Rather the curse of other people concerned may hunt such people. Any how this illegitable affair should not be encouraged and made an example by the youth and others who take the stars as their idols...!
