((((((Ellie)))))))
A few years ago, my T had to have an MRI on his back. I asked him how it went and he said "thank you for asking me, but I have a lot of support and this is about you". It kind of stung, but it did set a clear boundary and helped me not feel so much like I have to "take care" of T (something so completely ingrained and left over from my childhood).
I wonder if being put in the "caretaker" position - like you were probably in with your mom - was kind of triggering??
I completely agree that you shouldn't have to pay for these sessions.
You seem to have really good skills when it comes to working things out with T...maybe this weird situation will lead to more understanding and closeness in the relationship.
