SimplyTG has good advice, but I have to sort of agree with S'pert, you should know what to do if a girl gives you her number and you are on this forum.
Not keen on his "fuck you" ..... although he may have been friendlier if you had reported your experience when you first met your 141 walkup ... did you post?
You say she has been calling for 2 weeks so her period is definitely over, so I have to wonder why she wants to chill out rather than work.
It would be good if you follow through on this encounter and post your experience, sounds like it could be interesting.
