Every part of me is saying this is NOT OKAY! Your therapist is NOT supposed to kiss you on the lips. This is a major boundary violation in my opinion. Your best interests have not been met in this case. I'm not sure what to tell you to do, but I hope that you won't be too hard on yourself about this. I doubt very much that I would return to this therapist if I were you, but that is up to you to decide.

It is indeed an abuse of power, whether done with malice or not. I'm sorry you've been put in this difficult situation.
