I had the most succes when my bf was really threatened and scared I would leave for real, at that time he was ready to commit to treatment. Maybe this was also some kind of boundary - I was letting him know, I was not going to stay with him, if he is not getting into treatment and I really ment it.
I wanted to comment on this because, the reason this was effective was because it wasn't done for purpose of motivating the BPD partner- it was a sincere, feeling done with the disorder, and being ready to leave, actually meaning it.
Making any threat- without the intention to follow through- as a means to motivate or scare a partner is adding to the dysfunction. It can also damage the relationship and be diffucult to repair if it's done for this reason.
These relationships involve both partners. Each can be afraid of losing the relationship. If the partner without BPD doesn't want to lose the relationship - they may be more apt to walking on eggshells and have difficulty holding boundaries due to not wanting to upset their BPD partner.
When someone holds a boundary that the BPD partner doesn't want - the BPD partner then has a choice- respect the boundary or risk losing the relationship. This allows for them to make the decision. It's a scary one, as the non BPD partner may fear this risk- but it opens the door to the possibility of change, or the BPD partner may choose to leave the relationship. Sometimes when the non partner feels they can't continue, they have less fear of this, and so may be able to hold the boundary and let them make the choice. When someone makes their own choices- that is accountability.
There's a push pull to these relationships. Pushing too far, if the other person pulls, this can activate a fear of abandonment. This fear can be a motivator but a temporary one, as soon as the relationship gets back to "normal" the motivation is gone. There's a cyclic pattern to abusive relationships- the rage, the possible remorse, the trying again. It isn't just with romantic ones as it can involve other family members too.
If someone "pulls" as a way of getting the other person to respond- that is being manipulative too. It's engaging in the disordered dynamics and it causes damage to it. If a person is truly at their end point of tolerance, this then is acting authentically. The pwBPD will then make their own choices with that.
