I agree that psychoanalysis (or any type of therapy, really) is a commitment. However, he is acting very manipulative and I think what you’re picking up on (him taking advantage of your vulnerabilities) is spot on. It’s unethical to coerce a client into staying with the therapist (using tactics like “you waited 6 months to see me” or “remember all the bad therapists you had before me”, etc.). Therapists might recommend a client continue therapy if they believe it’s for the client’s benefit, but what he’s doing is extremely inappropriate. He sounds incredibly narcissistic.
