I know it seems semi-encouraging, but don't put too much stock in one day's attendance at counseling.
When I finally told my husband it was over, he flipped out. His therapist was gobsmacked---seriously, he was so flabbergasted at this response that he asked me in for a reality check.
My husband had told him lies about me ad nauseum, and the IC could not fathom that there was ANY way he wanted to be with me. And you know what? He really didn't. He didn't want to be with me. He just didn't like the loss of CONTROL.
Watch your husband's actions over time.
