I reread my post, post 54, you responded to with that question, and I wrote nothing to invite that type of question.
That post was discussing spouses abandoning a severely ill/dying spouse when they became ill.
My answer to your wondering is simple. Google it. You will find quite a bit of information out there to browse on that topic. You will wonder no longer.
And the point of the thread was about cohabitation, and the wisdom - or lack thereof - before marriage. But you can never let go of an opportunity to subvert a thread to express your own bitterness.
Humans have biological needs, and millennia of very wise people have approved the institution of marriage to constrain and constructively direct those needs.
The fact that you are bitter about how divorce is often litigated in this country doesn’t give you the authority to condemn a time-honored institution - and your expression offends the many people here who believe in marriage, and have had good, lifelong marriages to prove it.
Poor you.
I’d have more respect for you if you would get out of your armchair, and spend some of your vitriolic energy on actually working to CHANGE the things that you see wrong.
But I guess whinging and posting on the internet are easier.
