I'm lost. need help with WAW

[GAL Man]

After the convo on Sat and going dark for a week and a half I thought I would test the water with something else yesterday.

I left W a voicemail just saying that I had a minute and wanted to let her know that x festival was being held in x in Aug, and I knew it was something that interested her. That was it, didn't ask anything else. She obviously didn't pick this message up as within half hour she had called me back saying she missed my call (I let it go to voicemail) then sent me a text saying the same. Then an hour later she sent me an email saying that she had missed my call and asked if anything was wrong. I waited 6 hrs then replied sounding very upbeat, saying hi, no nothing wrong, all is good thanks then repeated my voicemail message. She replied back by email straight away saying, and quote "Hi, ohh thanks for that! Had a busy but good day!!!". I look at this as she was expecting or hoping for something else.

I called her on the way to work this morning as I wanted to get some help with a HR issue which I had, we had a chat about it, then I said right, thanks for that. W said ohh OK, then I said bye. Again I think she was expecting me to ask things, esp about us, but I didn't. I then text her to say thanks for your help, have a good day, and she replied straight back, no probs!

She is now posting on fb again, and I think she it playing tit for tat with me as her last post was about how she can now get back into her smaller jeans, as I posted similar last night. She is obviously not eating properly either.

I think she is questioning her decision, should I test the water and ask about us, leave it, go dark, be friendly, I don't know what approach I should take now
