Hi Siemprereal!
You are doing great. I am not an experienced PUA, I'm jusy going to give you my thoughts.
It seems that she's into you and she wants to test you congruence. Are you going to stay cool or are you going to become jealous and enter her frame? If you fail her shit tests she will loose interest.
Stay cool, be confident in yourself and continue to laugh at her shit tests or better still stay in control of the frame (ie: when she sends you message about how great she looks you can reply by talking about her personality). If she crosses the line give her an IOD followed by an opportunity for her to make it right.

What are your intentions? Do you want to become official with her or do you prefer to stay in the dark fuck buddy?

Good luck in you game bro!
