I brought that up to my T once.
She said I am only paying for her KNOWLEDGE--for her brain. Its impossible to pay for her to care about me. She said her heart is NOT for sale. When my T says she loves me, I know its because she means it-- not because I pay her to.
I have seen T's before who I paid well (lots more than this T) who definitely DIDNT care. So obviously the caring is not an automatic part of the payment process.
Its just the knowledge and experience you're paying for. Not their heart.
