Does this therapist provide any opportunity for both people to speak individually with them? If so, you could express your concerns about couples therapy with him at that time.

Also, a good, experienced couples therapist will be aware of, and deal appropriately with, efforts to manipulate.

Note that if your husband consistently acts like an abuser in therapy, that shows you that, well, he acts like one because he still is one. In that case, he hasn't changed.
