Welcome, Strongone!

You really have been through a lot. I'm so sorry. But I am glad you've found us here. We're a caring, supportive community and we "get it."

Collectively, we've experienced the full spectrum of BPD. Some of us have chosen to stay in relationships and work to improve them. Some have left. Either way, we have advice and experience to share.
First of all, the claims of abuse and violence. That's, unfortunately, pretty common here. Have you looked at this thread:
https://bpdfamily.com/message_board/index.php?topic=87480.0It's specifically about DV against men.
There's a lot to unpack here but we can help. No one here will tell you to stay or go. But we can help you come to that decision and then walk the path with you when you choose.
What, right now, do you see as the main issue you want to address? What would be most helpful to you?
