yes, i felt the same thing, hence my remark about our openness to roles.
perhaps it has to do with E, or our enneagram types or instincts, or just other individual personality differences, but i fall to the side of being very interpersonally adaptable. i can easily see myself being more social, or more socially aware, or more confident, or any other adaptation to fit another person, because i am doing that all the time to associate with people in general, as well as just by myself for fun, to meet my own feelings. similarly, i try to meet people in the middle, and i consider adapting myself to be a useful part of that. i do not feel like i lose myself when i do this.
so if a certain trait or behavior is more likely to make a crush of mine willing to consider me as a partner... then i am usually very open to it, provided it doesn't clash majorly with my personality. there are some things i cannot be - authoritative, fastidious, aggressive. but there are so many others. i don't even do it consciously most of the time, i don't think. i can say with certitude that it has been useful in my close relationships, though. in several cases i can think of how adapting to the other person has made
me better, because my desire to be appealing to them causes me to push myself harder. i tend to go for ambitious types... so i usually have to step up my game
