However, one of the things I am reading in the book is that you cannot force the BP to get counseling they have to want to get help; by saying "Get help or no support" isn't that a way of coercing her/giving her an ultimatum?
Looking back over this thread... .I didn't want you to think I was dodging this question.
As a general rule... ultimatums are bad... .
However, most of the times people issue ultimatums and then backtrack. That teaches your pwBPD that "resisting" gets them something. So... next ultimatum... they will... (you guessed it) resist, because there is a payoff.
If you really aren't going to have much of a relationship with your wife unless she embraces and deals with DV... .then I don't see a downside to an ultimatum. She needs to know her choices. It's not your job to give her choices that she likes. Especially if those choices flow naturally from her actions.
She does DV... .unpleasant things happen in her life.
She seeks treatment and complies with treatment... .relatively more pleasant things happen in her life.
How you deliver the ultimatum matters. You want to give her the best chance to "hear" it possible.
In the end... .it's a best "chance". Sadly these boards are full of stories where pwBPD seem to believe they are entitled to hurt others and suffer no consequences. If your wife chooses to be in that category... .we'll support you since that will undoubtedly be hard to accept.
Can you tell us more about the story? Your wife's history of DV?
You know her best. Do you think she realizes she has done something wrong?
