It doesn't sound like you've been seeing this T for very long... could you find someone else? Invalidating your pain by suggesting it's a psychiatric disorder when it's the first time the T has seen this reaction from you seems like a huge leap on the T's part. And it feels like taking sides with your H as well. Saying older forms of therapy are "dangerous" is also a warning sign, because different people find different modalities helpful. Does he think that only CBT is ever useful? If that's the case, are both of your families of origin just off the table in terms of discussion? I would totally run the other way and never go back to that T if it were me.

ETA: I think CBT is the "new standard" because it tends to be short term (so insurance companies love it) and it's easier to study in clinical trials because it can be standardized into a "one size fits all" process that's the same (or almost the same) for all the study participants. This leads CBT proponents to say it's more "evidence based" than other types of therapy. It truth it's just easier to standardize, so it's easier to turn into studies, data sets and research papers. Neither of these strikes me as a plus, personally. I actually really like CBT for self help, I just disagree that it should be the "new standard" in therapy.
