I’m a college Prof, there’s been a lot of s***** tension between a student and I. She stays behind after classes, stands close-ish to me and she talks about whatever is in her head. I think she’s hoping I will grab her and we’ll start kissing. A couple of weeks ago I bumped into her in a museum, it was uneventful, we walked around and spoke for about 45 minutes, her boyfriend was there. Since then she hasn’t come to my class. Why do you think?
