LOve should be the basis of any relation...no matter live in or marraige.....and if 2 people are in genuinely in love and are also in live relation they can eventually get married ...Its their own choice the society doesnt have to do anything with it...the problem in marraiges is that both the partners take to each other for granted and thats where things can start going wrong.. In live in relation both the partners know that the other can walk out of it so they tend to behave in a more responsible way...I'am not against marraiges but both of them need to put in some efforts to make it happy.. A relation cant be pulled on and on by one partner..
