For me, long story short cause I'm more curious to hear your stories, it explained the dynamics in my previous relationships, and there was a pretty clear pattern of the more alpha/beta I acted, the better/worse they treated me. Like, my worst ex would be mean to me and instead of standing up for myself firmly / asserting boundaries, I'd calmly explain that she made me feel bad, and then she'd get even meaner the next time (I'd basically fail shit test after shit test). Or, with my first ex I was super confident and DNGAF (even to the point of playful sexual cockiness when I first met her and flirted with her), and it was a very smooth and chill relationship the whole way through.
