It's fine if he doesn't want to switch his individual therapist but for couples counselling, it needs to work for both of you.

Granted, the female T is an unknown quantity. I am hopeful that, at the very least, she can't be as bad as the male one with whom you wasted a year of his incompetence. That is a long time to feel unheard, invalidated and stuck.

Remember, you are paying him. He works for you. IF you are not happy with the services provided and are basically not getting what you are paying for, it is wise to move on.
