that was an entirely inappropriate conversation to have in front of a 14 yr oldl!!!! wrong on so many levels.
regarding the therapist, to accuse your husband of cheating IN your therapy session crosses a line, in my book. and then to take it even further and tell what TYPE of cheater she thinks he is? how is that helpful or therapeutic??? hard to believe that after this length of time in therapy, the conversation is stlll about..........HIM.
