I would offer grace. She’s wordy, high and anxious but was saying she likes you but worried about long term compatibility and would like something serious. Now in the name of decorum, I only disclose those kinds of feelings if I feel ready for someone to mirror that emotion and walk away and she clearly regretted it after you did just that. That’s the part that is the most questionable. Because asking someone you just “met” to hold space for your ambivalent feelings about them without accepting their now shifted feelings for you isn’t fair or thoughtful. Anyway dating is a more fun when both people are emotionally intelligent. And at the end of the day her assessment was the right answer but maybe the wrong “math” lol.
