Been there. The psychiatrist was married. When I asked about his wife- "doesn't she miss you?" He said, "She has a picture of me." Three kids.
Never expected him to leave his wife, though he hinted he would. We were intimate...and more. It was a disaster.
Fast-forward more than twenty years- they are still married. She stayed with him even though he was arrested for keeping a 19 yo female patient against her will and had sex with her. She stayed with him even though his medical license was revoked for dishonesty and sex with patients. She stayed with him even though seven women reported him to the medical licensing board.
If he's hinting (or flat out saying) that he's in love with you, leave. Therapy isn't happening. You are paying him to talk about his problems? You are paying him to hint around like a child?
I've said this before and it's true- therapy stopped for me the minute he helped me with my buttons...probably before then.
