This. I think there are some dealbreakers, like ethical violations, but the fact is Ts ARE going to make mistakes. Some of the most healing work can be done in recognising and repairing these.

If you've been abused or neglected, it can be very powerful to have someone say: it matters if I mess up. I remember one day, soon after I started, my T said: "There will be times when I break your trust," and talked about how sometimes he'd get it wrong and we'd deal with it. And I thought: wow, it matters if you get it wrong?

I think it's impossible to get it right all the time, so there's no point expecting it.
