Hi Juta! Welcome to the family!

You'll find there are many people here who understand what you're going through. We've been there (or are still there) ourselves.
Life with a pwBPD can be difficult, absolutely. There are some very real challenges, as you've discovered. But, there is hope and things can get better. We have a lot of tools, tips and experience we can share that can help. It takes work, but it can be done.
I hope you don't mind if I ask questions. Details help us to know how best to help.
You say he's punishing you constantly. Punishing you how?
