Marriages can't fail people... People can fail in marriage when the do not make a complete commitment to it... SHE failed to do that.. miserably..
And yes, part of her failure was her lack of exposure to good marriage in the first place... when this happens, people often don't have the confidence or hope to try when the road gets bumpy... they run for cover...
I suspect the next time you pursue marriage you will triple check your spouses cultural exposures far into her past, and her families commitments as well...
Flighty people breed more flighty people...
Hard to say it, but if you want success. genetics makes a difference... if you want to go for the underdogs, I salute you, but you are on an uphill battle (one I am on myself)
