Wow, I am so sorry that this happened...there is no excuse,period. Thinking about what you just went through makes me feel like a schmuck for being upset with my T a few days ago for something far less offensive!!
I think depending upon how your relationship has been with your T prior to this incident and how she attempts to make this up to you should determine if you drop her like a bad habit... or not.
Really though...I think of how I would have felt if that happened to me and I already know...NOT GOOD!!! I feel for you and am hoping that you and your T can work through this...but if you don't feel like she is sincere please consider finding another T...hopefully one that is a little closer to where you live...sending hugs your way!!!
