Why does she ignore me? ...Maybe power because she knows I’ll come back to her, and she’ll get away with whatever she did.
Have you thought about how you could respond differently, to change her behavior (i.e. diminish or delete her use of the silent treatment), and maybe effect a change on the power dynamic over time?
She keeps using the silent treatment, because it
works for her, right? After all, you always apologize. But does her use of the silent treatment work for you? Does it feel good to be treated like this? No, right? So do you think there could be things you could do differently, so that the silent treatment doesn't work for her anymore?
When I was a kid, my dad always forced me to apologize even when I wasn’t wrong, and my mother never reciprocated. She would ignore me until I made the first move towards repair, which still happens to this day. It feels unjust.,.,like illogical thinking and harmful behavior wins out. And she always wins, because I want to have a relationship so I always make the first move towards repair.
There's a lot to unpack in this. Why do you think your dad forced YOU to apologize even when you weren't wrong? This could be a really important thing to think about...and lead to some understanding of how her BPD affected THEIR relationship. Like you, he had to survive...
Her ignoring you until you made the first repair, as you said, is about power. It is a maladaptive strategy to manipulate you to have her needs met, which sets up an unhealthy relationship. This would be part of why you are so bothered. Nobody likes feeling manipulated, and nobody wants to be pressured to apologize for something they have nothing to apologize for.
Despite her treating you with the silent treatment, and abusing that power with you, you want to maintain the relationship. If you don't mind my asking a question, I am wondering "what you are getting from the relationship that makes you want to maintain it, despite her bouts of silent treatment, and the demands for apologies" (when you have nothing to apologize for)? By this, I am recognizing that a relationship with a pwBPD isn't always bad. There can be some good things or good memories too. But when it's bad, it's bad (your words!). This is perhaps a complicated question with many layers, and not one you need to answer here if you don't want to, but perhaps something to think about.
Here are two links that could fit for you:
1) Don't validate the invalid (don't apologize when you have nothing to apologize for. This would be validating the invalid).
https://www.bpdfamily.com/content/communication-skills-dont-be-invalidatingThe entire link could be helpful, but the paragraph that is titled "Remaining True to Ourselves" speaks particularly to not validating the invalid.
2) "Silent Treatment" (forum conversation)
