That strikes a chord with me. I can understand a second marriage since a person may have been very naive and married someone he or she didn't really know the first time. But the third time, no, something is really wrong with you if that happens. You either have poor judgment or you don't hold to your promises.
As regards multi-marriage people in general, though, do they not understand the pledge of "to have and to hold, from this day forward, for better or or worse, for richer or for poorer, in sickness and in health, to have and to cherish, as long as we both shall live?" Maybe that last phrase escaped their memory or they never meant it in the first place.
I remember it well and I abide by it. It's been 41 years now in this, my first and last marriage.
41 years, congratulations!
You know, early on in life I always assumed saying congratulations to people for multiple years of marriage was just an empty nicety. As I grew and learned (having been divorced and re-married for 12 years now) I found out why people congratulated each other for this...
It is work to follow through on this commitment. You have to be able to communicate and rationally discuss your wants, needs, desires, your true emotions.
You have to lay bare all of your emotions and be honest about how things make you feel. What a naked feeling!
It is real work and it takes an immense level of trust to confide so deeply in someone else your most raw personal thoughts.
That is why we congratulate each other on this true accomplishment - because we are able to have a proper adult relationship that continues (hopefully) into eternity.
