Quote Could she have borderline personality disorder?
I spent 22 years trying to figure it out and have literally read or listened to hundreds of books. My final conclusion I came to was, it isn't my problem anymore.
The reason I ask is because she IS your children's problem still. Borderline personality disorders swing between "You're the best thing ever" and "you're the worst person I ever met". It's so confusing and disorienting for people who are involved with them. They have trouble maintaining long-term relationships, friendships, sometimes jobs because of it.
My best friend was raised by a stepmom who is a (relatively benign) borderline. This stepmom did manage a long marriage to my friend's father but he was extremely codependent. My friend says the stepmom can be a lot of fun when she's in a good mood, but can turn on a dime if she perceives some kind of (usually imaginary) slight. Stepmom and dad moved a lot, stepmom either didn't fit in or wore her welcome out with various friends and church groups. When she married the dad stepmom threw away almost all photos of my friend's deceased mother. After the father died she threw out a ton of family photos without asking my friend first if she wanted them. She's finally moved out of state to live near her biological daughter and although my friend misses the good times with her, she realizes how unhealthy the stepmom is and is happy not to be walking on eggshells all the time caretaking her stepmom's "feelings".
