My ex T is insanely wealthy. Her husband is a lobbyist, she lives in the most expensive part of my town, her kids used to go to a super expensive private school. She's loaded.
At the time I was seeing her, I had money problems since I was between jobs for some time. She could not relate AT ALL. Like it was almost offensive how clueless and in her bubble she was being whenever I talked about money.
For instance she would suggest for me to do activities, travel, go back to college, etc. And I was like: how am i going to pay for this??
So I stopped talking about it. But I had some resentment for the way she handled things.
So I completely understand where you're coming from with your therapist.
My current T is alright financially I think but she's not super wealthy either.
Differences in terms of finaces don't make me feel inferior, I just think sometimes therapists can't relate and it can be an issue.
