Mind games of women *HELP*

[Escorpio]

Need some advice from experienced bros out here. There is this girl that work in the same department with me for around 2 years already, our table are just beside each other and we always have small talks during working hours and she always seem to be laughing at my occasional jokes and enjoying the talks. A few days ago we needed to work on a project together and since she is more experienced than me she need to teach me more about it and during the 1 to 1 we seems to be enjoying ourselves, after the project she posted on her Facebook, "please make it the last time" then I was damn paranoid... It's like right after the project, and it's seems to be directed at me. What do you think bros? You think she playing mind games or just I really gone case alr? Stress, cause I interested in chasing her.

used to tried to chase her, she used to always text me then can text with her all night long for a period of time (1 month ++), chat can last from 9pm - 3am but then I stopped halfway. everytime jio her out she like don't want don't want like that... She is quite a player got a few bf in less than a year time. She always send mix signal to me, can make me feel like king one moment then make me feel like peasant the next. How to test water any tips? Help needed here bros!
