Marrige is 80/20????

Hummmm, I  just heard Neal Clark-Warren make a statement that Marriage is an 80/20 proposition. Each partner gives 80 percent and only takes 20 percent. I disagree. If all you HAVE to give in to a relationship is 80 percent, that leaves that other 20 percent to be given somewhere else. Doesn't matter if it is only 20 percent you have the option to give away to someone else... ANY room for compromise only wedges room for 21 percent.. then 22 percent..... and before you know it.... you are way over ====> there with no idea how you got there.
Marriage is 100 percent devotion to that person.... giving 100 percent of yourself to that person.
