I'm so sorry. This sounds absolutely awful, especially within the context of having worked together for five years.

I had a similar experience of feeling like, after six years of therapy, my T forgot how to empathize. The new T I've been seeing really seems to get me though. I'm surprised by it, to be honest. I'd encourage you to seek out someone with expertise in working with people with infertility concerns. I never thought I'd be one to say that it's ok to move on, even after a long T relationship, but it's been extremely helpful for me.

Hugs to you!
