A brief history of marriage.

I have never believed humans were meant to maintain one relationship for life.
Some animals do?
I don't understand how that is relevant.

Human beings grow, and change so much in a lifetime, often several times over.
To believe we would find a single person who would grow and change at the same pace, liking the same things, wanting the same life and altering to suit our physical tastes all at the perfect moment, seems crazy.

Of course it doesn't have to be perfect all the time, but you don't have to flog a dead horse either.
As you get older you change less, so it's easier for things to last longer.
I have found as I get older a year in a relationship is nothing, thAt I am just going along doing my own thing and if my fell wants to join me, that's,awesome, if not. I Will catch him on the flipside. We do ok.
Oddly enough though I still feel marriage is a one time deal. Funny that. :-D
