Yes, seek a different therapist, although at this point she might not be game for that.

Before you even see a counselor you should make sure to talk to them on the phone for a few minutes. The question you need to ask is 'What do you see your role as being when one spouse does not want to work on the relationship, and at what point do you feel it is your job to recommend they both give up?'

If they say anything other than 'my job is to facilate improving the relationship and work with whichever partner is willing to make changes, and not to recommend divorce. That is up to a couple to decide.', keep looking.
