"In a country like India, it is not a good practice like live-in relationship. Actually, these kind of relationships are the idea which crop up in the mind of mentally ill people" My friend Anil Gogia. I dont think you under stand the concept correctly here , live in relationships ae for romantically entwined people. Now if you tell me if its reasonable to have live in relationships with your siblings and parents ( believe me this is known as INCEST and is very much a fact of life in India like Homosexuatlity just that i needs to come out of the closet).
"Actually, this is an illegal arrangment between the two to enjoy phisically and when their urges are fulfilled, they get separated" evere heard of term term mutually consenting adults ? , illegal or not let the country's leagl system define it - as of now it is not illegal.
"Trust" is the basis for any relationship for the matter even a live in relationship demands trust to a larger extend. I feel liveins demands more trust than a traditional marriage situation where in people are forced to stay together on the basis of commitments.
