There is no such thing as an unbreakable frame, you might think you have an unbreakable frame but for another person you have a weak frame, it depends on the culture, your personality/his her personality, upbringing, values, etc. For example, one situation X occurs, you react a certain way and you think you maintained your frame, but the girl you're dealing with might think the opposite and vice versa. This frame thing ok, yeah but nobody is a robot, we all slip sometimes, nobody is perfect. I had episodes of "weak frame" in the past and I was still able to get hot girls, other times I maintained a super rigid/unbreakable frame and got ghosted and nexted.
This frame thing, it doesn't mean anything really. It's old pua stuff.
I understand the idea yes, but unbreakable frame... come on.
