>Start telling her about my deepest fears and demons
This is your mistake, anon.
I've done this too (about 'tism and 'being inexperienced') and gotten ghosted by old foids who had claimed to be DTF.
That said, you should go fuck the second chick if she is still texting you. I never get those.
Foids love confidence/disinterest, and hate men admitting their failings and insecurities.
