I think you are right about my W. She has not been one to ever seek help for herself. It's almost like she lives in denial that anything is wrong with her. But, she will occasionally say she is worried she will end up like her mother (who is not healthy at all - I suspect a Borderline Personality Disorder).
My W almost never apologizes when she is wrong. She will defend herself until the end and until the problem goes away on it's own.
I've seen her have HUGE blow ups with her family members. Then she gets really sad and compromises her view point with them and reconciles the relationship. But with me, she would defend herself to the end.
