Last night I saw something that I hadn't previously. We went out and he was calm. Rational. REASONABLE.
... .
Then he told me that if I wanted to walk away because he wasn't "good enough" that he understood.
Ummmmmmm... .
Ummmmmmm... .is exactly it.
I'll grant that he was behaving better than he often/normally does when he said that... .
But a well-adjusted/sane person would never need to say that to their partner. Ever.
Because it is either manipulation or poor boundaries. If he had good boundaries, he would understand two things:
1. Either person can choose to end a r/s you are in at any time, without needing the other's permission, blessing, or anything.
2. Inviting your partner to end the r/s is just messed up. If you want to end it, do it. If you don't want to end it, why push your partner to do it for you?
Of course, he's got BPD and has poor boundaries, and thus you get to think about the best tools to use in a r/s with him, and what to say when he pulls this on you. A couple come to mind.
Ask about his feelings in an attempt to validate?
Just move on and not take the bait?
