This sounds a lot like my experience with my ex husband. At first, he took out his aggression on objects, later on me. Like you, I kept this secret from family and friends and over time, became further isolated and estranged.
I’m glad you are reaching out. It is a huge burden to bear and those of us here have similar experiences and understand.
People with BPD (and NPD too) have a lot of internal shame and self loathing. It’s really hard for them to hear criticisms or complaints, and sometimes just hearing someone else’s problems seems like it cuts them to the core and they act out in ways you’ve experienced.
Expecting empathy and understanding from them is often impossible.
So he’s been diagnosed. Is he in therapy?
Thank you so much for your response! Having someone acknowledge this thing I'm going through means the world to me.
He has been diagnosed by a professional about 4 years ago but he never did any kind of therapy. I occasionally try to bring it up and convince him that with time therapy really does help but he doesn't want to hear about it. He either says it's not the right time or he gets angry if I insist.
I, on the other hand used to see a therapist to help me cope with his behavior but at one point I simply stopped because no matter the discussion or argument we were having he kept saying that all I do is try to feed him all that psychotherapy bulls***.
So, to keep it short, he is not in therapy nor is he interested in seeing a therapist.
