Besides things like playing with jewelry to draw their attention there, or look backs.

Is there stuff as a guy that could help me? I don't know if this lady coworker is into or not...the sheer amount of history and development over almost 3 months now is confusing me. She even asked me to walk with her down to the front lobby before the turnstiles, which i fumbled the 1st time, then she tried 2nd time and I did...we didn't go past that to her car but...lots of eye contact for like the first 7 wks maybe? And now she's more "no" recently. Mixed signals, am I just dumb, or worse am I somehow projecting??

Any help appreciated...if not obvious I'm writing tired AF so...yeah that factors in my writing quality above.
