1. Its individual preerence whether to marry or to live-in. In upper middle, upper and lower strata of society, living-in is so common. Only the middle class, who lust and fear of everything worry about any concept.
2. It solely depends on a person, to choose his religious, societal, cultural spheres of life etc.... according to constitution, living-in is LEGAL.
3. If there's a physical or emotional or financial incompatibility between the pair, better is to try out live-in, and if both like each other's company and are confident and excited about taking the relationship further, great.. (recent survey says 33% .. that is 1/3rd of most Indian men do not measure up and also are prone to infertility and have ED and PE.
4. In any relationship, people need to understand and live happily.... not to ADJUST. In many marriages, (marriage - also called as legalized prostitution by philosophers by the similarity in ideology) Indian woman are the sufferers... Now, we see economic and societal freedom accessible to many girls who are capable of deciding their future.... its their sole choice...
5. If someone here gonna say only marriage, religion and customs make up Indian society, better read history..... Its known for ages that Indian Society is made of acceptance of new thoughts and tolerance.... Religious people can refere Rig veda.. which says in its 1st Phrase.."let ideas come and be accepted from all over the world"....
Y should society try to stop anything before tried?
