(((((Elysium))))) I agree with everything that has been said.

This sounds really difficult emotionally. Putting myself in your position, Id feel terribly confused. On the one hand, you loved your t, she was there for you for 5 years. That is a really long time. And unless she kept you on for some kind of selfish, financial thing, I imagine she kept you because she cared for you so very much. So there was real caring, love and concern on her part and I would imagine strong feelings for her on your part. But she should have done the right thing. Deep breath.....

I think it isnt appropriate and fair as you said for her husband to refer you to his wife. And not say something about that. I agree with what has been said. Especially since he had to know in some way that she wasnt qualified (experience-wise or whatever) to work with you. That was the bigger mistake I see. She should have made it clear to you that she wasnt the t for you in the beginning. Maybe once things got underway she thought she could do it? And she liked you? The legal things you mentioned, well, Im not sure why she would have said that. Maybe she was afraid your chart would be called into court and she would have to testify to something. Not sure there, but I am so sorry she left you feeling so confused, disappointed and betrayed. She certainly did all of those things and you DO have every right to feel that way.
Big Hugs to you
