Yes, my therapist has apologized to me. And it was a real apology too, not a "I'm sorry you felt that way." He then went on to "explain" what he meant by what he said. He prefaced by saying something like, "I probably didn't do a very good job of explaining it," as opposed to "your irrational beliefs and low self-esteem made you interpret that wrong."...although truthfully that could have happened too.
