We met, she seemed interested, I spent a bit too much time in the getting to know her zone and after an attempted escalation about 2 months later she said she had started dating someone. Which was true, she had.

That was fine, I took that as a no and moved on. I still have to see her a fair bit but I stopped the communication and significantly reduced how much we talk when I see her, do the pleasantries and move on.

But now she seems fairly irritated at me. I see her glancing at me quite a bit and has this unhappy/angry look at on her face. When I talk to her she's extremely happy for us to speak and encourages it, but I keep that to a minimum and catch her giving me these dirty looks.

Anything?
