Ahhh slippery slope fam. Best move us to just carry on as before. Only way this works is if you get choosing signals, start "eye fukking" her, and then you see if she makes more bold moves after that.
I done been around bytches that will lure a nikka in and then take it straight to management when them texts start flowing in. And they cool ass females so you wouldn't expect it but there's actually a lot of people like that that will prey on another's weakness if know it won't take much effort.
At the job, if a bytch is choosing she'll tell you directly. She will not have someone else tell you because workplace appearances are important. Pull her number off to the side and if you can't, hit that eject button. If she ain't said (not playfully) she wanna see you outside of work, then there isn't much more to the situation.
Good luck i guess. I could be completely wrong in regards to this specific scenario but it's always better to be safe than sorry and jobless.
