This is just an extension of MWD's maturity principle...
She talks at length about a person in a relationship having the maturity to do what is needed to make a marriage thrive.
To her mind the maturity to Do this when you have the MOST obstacles facing you - your spouse is wayward, your spuose is cheating on you, you have cancer, etc is the most desirable quality in a mate. In short - Staying power.
THose with less maturity will run to a new mate (infidelity), run to their parents (mama's boys and daddy's girls), or they will simply run (flight risk)
In all three cases these three scenarios have that same thing in common... when the going gets tough, they RUN!
