Overall, communicating about it has been the most important thing.
He creates space for me to be angry. He wants me to actually tell him if something upset me, whether or not I think it "should" or that it's "unfair" for me to be angry. Sometimes it's irrational. He thanks me for telling him. He doesn't try to tell me why I shouldn't be angry or blame me. And he stays there, being calm and kind and safe and I know that I won't be in trouble or resented for being angry. There won't be any retribution or backlash. It's safe to let my guard down once I'm done being angry and hurt.

I'm sure it will happen a million more times because that's how I am. But being able to directly address it has made a huge difference.

Have you told your T that you're upset yet?
