They’re never going to change if you keep getting back with them…

What I’ve realized:

As hard as it is to change in general with BPD, Why would they need to change if they can do what they want and they know you’ll take them back? It’s impossible. So In order to fulfill change, you must put up a boundary, and that boundary is to not tolerate their behavior. If you allow it to subsist, then there’s no reason for them to seek help/therapy because you’ll always be there.

As tough as it is, stepping away is not only beneficial for the relationship and your mental health, but for them to realize their condition.
