Has anyone's exwBPD stated "you can't hurt me"? People with BPD are described as feeling too much, it seemed he didn't feel anything. My ex would reiterate that he doesn't experience normal emotions, happiness/joy/excitement, really just anger. That I could never hurt him (emotionally). On the other hand he would say things that made him seem terribly insecure, and when I said something that he took as "others have said the same thing and broke up with me" he bailed.
They live in perpetual pain and misery. They do not know how to be happy, they only know how to act happy. They do feel, anger, hate, love, pain. It's swirling inside them with no release. It's a sickening position to be in. Thus is why they are what they are. They can't process emotions properly. It's all acting on their part. It's why you can never get to the bottom of it. Ask a borderline how they feel, they won't know.
When mine broke down in front of me she admitted many things. She admitted to hurting people and not being able to stop. She literally BROKE, it was frightening, I saw the soul within.
"I don't know what I think or what I feel, and I'm sick. This is the truth you wanted, this is me"
That's a direct quote from a borderline who was telling the truth for one brief moment, and that brief moment caused her immense pain.
A cry for help, a futile cry because I couldn't help. There was nothing any of us could do to help.
She could never ever admit it to me again and I think she can rarely even admit it to herself and 99.9% of the time denies having a problem. But I always will know the truth, and that truth applies to them all.
Try to act with compassion and dignity. They have a terrible thing wrong with them.
