Joan suspects that the situation was already unsalvageable, that there was little a therapist could have done to fix things, that what Ted thought they had was already gone. He's absolutely right that the therapist should have created a space where he could be heard too...the therapist was pretty obviously already on Michelle's "side" as it were, and she probably shouldn't have been their couple's therapist for that reason. But Joan suspects a different therapist wouldn't have made much of a difference in the outcome.

Joan puts her hands on his arms and leans back into the embrace, closing her eyes. She loves him so much, and his pain makes her heart ache.
