Ok, for some people it is like this:
Quote:The desire to cohabitate without being legally married has to do with not wanting to conform to traditional values concerning romantic relationships. These individuals may feel that they don't need the government or organized religion to make their relationship a legitimate one.
The line between co-habitation and come-we-stay unions is a thin one. Infact, to most, the two are the same. And the line between marriage and co-habitation seems to be a thin one and sometimes arbitrary too. But as things stand, a Marriage Certificate would still come in handy at times.
