I am sorry if I have got this wrong but is Madame T both your therapist and a woman who you were in a sexual relationship with for 10 years?

If so, I don't think that it is a good mix - it will be hard for her to maintain her professional detachment towards you as a client without remembering your previous private relationship (counter-transference) and also hard for you to consider her professional advice without remembering your previous private relationship (transference).

Again, apologies if I have got this wrong.
