Well, there are evolutionary reasons why the custom of marriage came into being in the first place....read the foll in terms of how life was back in the stone age (well, you know what I mean!)
1)property rights for the spouse of someone who dies (esp the women)
2) making sure the husband sticks around to provide for the family (coz it was the men who provided) If the law binds you together the man is less likely to wander off and not take responsibility.
I cld go on but these are some reasons...and now with the changing world, with women being increasingly independent you see a corresponding increase in live-in relationships.
So marriage is really abt security. Even emotionally, it used to be that if you're married then you're stuck together whether you like it or not! So it makes you feel more secure abt your partner....and then they fixed that problem with a wonderful concept called 'divorce'!! Now we just hope and pray that our spouses will not fall pray to the 'grass-on-the-other-side-is-greener' syndrome......
To finish....is marriage necessary? NO!
Did it come into existence for good reasons? YES!
P.S. I'm using the term 'evolutionary' here in a loose, non-genomic sense...
How well you have put it!
