That line in your post also stood out to me, as did your assumption in a previous post that she must have found you to be a "creep." You're projecting a lot of stuff onto her non-response, and I'm sure it must be tied up in other wounds and hurts inside of you. I hope you can be gentler with yourself; I really doubt that she's annoyed by you.

As Bill3 said, she may just be sticking to set boundaries. Or perhaps she was busy and forgot about the e-mail. Perhaps she's not good about answering e-mails in general.

If I recall correctly, she's an adjunct professor, or something like that, right? Truthfully, you're very unlikely to find a "mentor" in an adjunct. They are overworked and underpaid. From my personal perspective as a professor on a lectureship at one university (50 students per semester) and an adjuncting gig at another (100 students per semester), I am always glad to hear from former students, but I'm not always great about e-mailing back. I have many students who need my attention during the semester, and when I'm on a break and not teaching, I'm doing some other work (my own, or taking on another job). I simply don't have the time to engage in much correspondence with former students, though I care about them very much as people.
