Sounds like it all worked out really well. That's great your T called and invited you to come back. I have a lot of respect for people who take responsibility.

I think you're being kind of hard on yourself with the borderline comment. Why not, "I was really mad so I left"? Or maybe it as an effort to set boundaries: "I won't continue this conversation unless he owns up to his part in what's happened here." I think you did really well.
