Yeah, your therapist crossed the lines asking you about your sexual preference (why is that her business anyway), about your previous relationship to your therapist (not her business either) and then divulging her own personal life example where she was attracted to one of her own patients. You were right to lose respect for her. And frankly, why would you entrust her with your mental health treatment now?

My opinion is that you're better off going to a walk in counseling clinic being seen by graduate students instead of staying with a licensed therapist who has terrible boundaries.
