I guess I don't now.

I guess bec the institution of marriage on this big blue marble is religious based for many. The idea of staying with this other person till death is pretty significant.
The top religion in the world is Christianity at 2.2 Billion followed by the Islam faith at 1.6 Billion so I think just a few of those people think marriages should last forever. Or maybe their all lying?
The Hindus, I've not fully researched.
So I'm talking here about this institution of marriage & how it is viewed by these billions of people. Not the poly population or the common law people who I'm guessing make up a small percentage. I'm looking at this vast word of marriage "globally. "
And I really don't think my background has anything to do with this conversion per say. I know people are individuals & have their own outlook like you say, very well, but I was trying to push past that.
In fact the thread was supposed to be a bit humorous bec I compared it to leasing a car! Maybe asking for a certain model car or technology updates etc.
I'm sorry if this thread has gotten you annoyed. It was just a thought process.
Sorry.
