I have a somewhat similar opinion. I have said, it's never 50/50. Both partners have to be willing to put in 51%, or more, all the time.Precisely! A commitment is meant to be serious. The problem in the world today is that we've allowed it to become a "Me, me, me" world.
"It's become all, my way or the highway."
The reason both sides of my family grandparents stayed married was because of morals and ethics, and because they didn't expect to "win" every discussion.
To me, any marriage, or serious relationship, needs at least a 75%/25% "give in" ratio. Both of you. Be willing to give in more than half the time, and it will pay dividends.
But, nobody can give in 100% of the time because they lose their own sense of identity. You can't give in until you aren't you anymore.
That's not what I would call a relationship. More of an owner/servant sort of arrangement.
As a society, sadly we most certainly have drifted off course.
In theory, if you're willing to do that it should come back around to you when you need it. Unfortunately, "in theory" doesn't do much good any more...
