Slept with a college from Uni recently. It hasn't worked out (apparently I expected too much but I definitely didn't put her on a pedestal and I don't really care that she's somehow conjured this up in her brain because it definitely isn't true), considering some of the shit tests she was trying to give me immediately afterwards made me question what I thought about her so I'm not that interested in her and there is an awkward vibe now whenever I am in a class with her.

I've been trying to ignore her but she keeps always being there, her friends keep talking to me about her which is irritating (the old "she just needs time"... while she has another dick in her mouth) and she keeps asking questions related to work that she already knows the answer to. I ignore her but seeing her pop up in my life is annoying me because I've already fucked her, she's more hassle than anything else and I'm not being part of her story.

How do I get this message across without looking butthurt so she understands my opinion and may be class would have less of an awkward vibe? I've been ignoring her but the vibe hasn't changed but the same awkwardness still remains.
