Therapists can only go by what people tell them.
Agree w/that, tbddbt. By analogy, when I confronted my BPDxW about her drinking problem, she went to see her Doctor, who purportedly confirmed that she was not alcoholic and it was just stress. Yet I'm certain my Ex didn't relate to her Dr. that she was drinking a 12-pack (yes, a 12-pack of Coors Light) every night. So you can't go by what they are telling you, and who knows what the T actually said to your H.
