I would feel so angry at my T if they behaved this way and left me wondering what was happening. Also I can see how she moved the goal posts and didn't have the words to tell you after having another baby. It really messes with your head, the stress, hormones, tiredness...I literally didn't recognise myself for 2 years and still don't really.
I guess therapists are only human. I don't think reporting her would help, it's likely she is already suffering too.
It totally sucks that she couldn't communicate with you about your sessions tho, I'm sorry that happened.
