Hey Peaches - I hope it is helping some to talk about it here. I got some good feedback on my final rupture with my T by talking about it here.
When you are able to talk to T in person, you will be able to find out the true story in more detail, with her side included. It took my T and I a few weeks to work our that last one. He has since taken a new job - now I know what had him distracted from his best self!
If she had only written - "Oh, I am so sorry that I don't have the time right now to give this a proper response! With my sister in the hospital, I'm really "off-duty" right now. I promise to write you when I'm back at my desk and have time to think".
