I cheated on my wife. This event upset me and I feel the need to consult a psychotherapist. I love my wife and I want to do everything to save my marriage.
I am afraid though that, by talking with the psychotherapist, my wife will find out and will not be able to forgive me.
Can this thing happen?

No. All conversations during psychotherapy sessions are strictly confidential and are not divulged to anyone without the patient’s approval.

The patient has to know without any doubt that the information known by the psychotherapist will only be used for the therapeutic process and under no other circumstances.
That’s why it is not good to accept “therapy” by friends, relatives or family acquaintances with whom you are in contact in other circumstances from those
Involving therapy.
