I checked the first three options in the poll for how I would possibly do it, depending on the situation. In reality, I told both of my T's over email, I felt like stopdog, why pay for that. One of them did not accept it for a while and kept emailing, even called me out of the blue so I dumped him on the phone as well in a quite aggressive manner. I can imagine maybe wanting to discuss it and then I would do it in person, but that has not happened yet (to pay for a session just to do that). I wouldn't simply walk away without telling the T as I see therapy as a professional relationship and would consider not saying anything disrespectful, but it's me and I think it's okay to simply not go back without explaining. I did provide quite extensive explanations to them though because I felt it was useful for me and thought perhaps for the therapist as well.

My experience was that the T's did not simply accept ending without trying to talk me out of it.
