Women who played into classic female archetypes (i.e cool girl, manic pixie, dumb girl etc.) in real life but grew out of it, at what point did you realized that it was essentially a performance?

Edit: Would love to know more on your experiences while trying to perform said trope. Apologies if the title lack elaboration.
Edit 2: I didnt expect this much responses but thank you ??
Edit 3: To the people who have been asking/wondering what a Manic Pixie Dream Girl is: basically just means a quirky, spontaneous, eccentric girl (think Kate Winslet in Eternal Sunshine, or Zoe Deschannel in 500 Days) whose sole purpose is to bring the typically recluse, depressed or broken man out of their comfort zones and live life or whatever. In real life, the MPDG may manifest differently and those experiences are what I'm looking for.
