@statementstate you have been the victim of severe abuse. You are not to blame for it. You still care about what he says about you and his accusations because abusers are excellent at what they do sadly. Because they are “good” at what they do ie: undermining you, distorting reality, threatening you and people around you, making you feel guilty, making you feel powerless, making you feel hysterical, it can be hard to feel like you are fully out of their power even when the relationship is over. It might be awhile before you fully feel you are out from under his game and his rules.
I am not an expert in BPD but I do have a some background in psychology and a good working knowledge of domestic abuse. I can’t diagnose you, neither can he. However, accusing a female partner of some kind of psychopathology such as BPD is extremely common among abusers, as is the counterclaim of abuse. If what you say is true, I fully trust that it is, you have certainly been victimised by an abuser.
I recommend you read “Why does he do that? Inside the minds of angry and controlling men” by Lundy Bancroft, as soon as possible if you haven’t already. This book will help you to understand what has been happening to you.
Please don’t pay too much attention to any posts giving you a hard time. Abusive people are very hard to deal with and can be extremely dangerous. They are very skilled at controlling people, they may seem out of control- but seeming out of control is usually their way of staying in control of you. It’s a shame that there isn’t more education around it, but there isn’t. Abuse can happen to anyone, it isn’t about who you are, it’s about who they are, you were unlucky. Everyone is confident that they would never put up with X,Y, Z until they are faced with the kind of abuser who really knows how to manipulate them.
I would recommend, when you are ready, finding abuse survivor support groups online or locally, Therapy with a therapist who has expertise in abuse is important (this is not a very common specialty so make sure to research carefully). Get help from domestic abuse organisation like Women’s Aid, ask them for advice on how to get appropriate legal representation.
Take it one day at a time, you will be okay again soon. Good luck 💐
