The only reason I find this a bit worrying is because in most of your threads you talk about how strong your transference is with your T, how you sometimes go crazy over her and how you can't stop thinking about her. Now she "rewarded" you with a visit at your work and then she invited you to go dancing with her. I don't see how this can be helpful to you when you struggle so much with the transference anyway.
But then, that's just me and who I am to talk really?
I just hope all this is not hurting you more.
