From what you described I would be really taken aback too. Ending your work together because you had a rupture? That doesn't seem right. I can almost understand talking about the distorted thought process of others and how they might affect you and how to deal with that (although coworker emailing you about finding you on a dating site = creepy). But if that's what she was going for, it sounds like she missed the mark.

Personally, for me, I would go back to my T and explain what was going on in my head during the session and see if we could come to an understanding giving her the benefit of the doubt that she was having a wierd day.
