Do you get any benefit whatsoever out of seeing her? If so, does that benefit carry more value than the frustrations you leave with? If you quit, can you go to another t? If not, is this t better than no t?

I guess if there is any positive to seeing this t whatsoever, it would likely be worth it to discuss what you are feeling before just quitting. Maybe it won't change anything, or maybe it will. Either way, you'll have peace of mind knowing you did everything you could to make the best of it.
