My T let me say I felt like punching his wife in the face. LOL. He didn't act that was totally weird.

Your T already knew that you were having an issue with this. He will know why you are so triggered, and I am sure that he knows that the third e-mail is a result of that. Unless you somehow threatened his child, I'm sure he's fine with whatever was in the e-mail, and you guys can talk about it.
