Relationship go with bond, give and take more than anything responsibility on each other. If it is a proper relation ship (legally bonded) They are answerable to each and everyone. There will be a social fear. The relationship of a Man and Women does not end with them, it continuous, What about their kids. This live in relationship is bullshit. And this is for Western opportunistic society not for our cultured society. If something happen they care only about themselves, least bother about others. We have orphans all around india, when we claim ourself cultured and if we allow this livein culture. We have to allot a state for the orphans. Be careful
