Hi mindwise,
1 - BPDgf gives hints she needs space.
- I let her know I understand and will be there when she needs me
- She does come back pretty quickly and I agree to engage her right away
2 - BPDgf refuses to see me for several days without explanation and avoids responsibility.
- I know it has to do with her fear of intimacy but disengaging in this manner feels disrespectful to me and our relationship. When she behaves this way I usually remove my attention (I don't reply) and wait for her to come back at her own pace.
- When she does comes back I tend to engage her pretty quickly. If I don't or give a hint I'm not satisfied with her behavior she gives me "silent treatment"
Makes all sense to me. She is doing because she has to. It sucks but there is nothing gained in heaping shame to it. Once in a while you should be talking about it not to judge but to better understand however... .
I'm wondering if the silent treatment is an "extinction burst". I never ever pursue or chase her if she gives me silent treatment. The longest silent treatment lasted for 10 days and when she came back she asked me how long would I have waited before contacting her, to which I replied "as long as it took you to come back". I think she learned ST didn't have any impact on me and from then on ST have lasted no more than 1 - 2 days max.
... .in some sense you are communicating about it.
No, this is not an extinction burst. Extinction bursts are directly related to boundaries that are encountered.
When she refuses to see me for several days she kind of expects us to text "as a friends" or "brothers". I state clearly that I'm about sharing quality time together in person, not through texting and that I'm not interested in just friendship. Something I've notice is how many guy friends, ex-lovers she has blowing up her phone and I understand this gives her a huge ego boost while maintaining them at arms length.
It is confusing and at times very painful to deal with a person who does not know what she wants.
You seem to have common sense of what limits you put on yourself

Still she seem to be regularly blowing up. Avoiding invalidation in communication is important as invalidation is a major source for emotional overload trigger - we learn that by focusing on validation and learning from what did not work . Keep in mind that avoiding her to storm off may not be a desirable goal - right now it works as a semi functional pressure valve. Boundaries are often also invalidating but serve some healthy purpose.
