I understand those mixed feelings. Honestly, I don't think she will lose her license from what you describe, so I think you should be okay on that front.

Reporting takes a lot of emotional energy and I think the decision you make should be based on your needs, not your therapists. So think about whether the possible outcome is going to be helpful for you, and whether it is worth what it might drag up.

In my view, the amount of time in practice is neither here nor there. If she is taking your money and calling herself a therapist, she should be behaving ethically and should not be gaslighting you.

Your therapist's empathy for your old T would irk me to be honest (in fact my T's initial attempts to understand where my first T's actions were coming from hurt me, so that might be affecting my response to that).

So I understand the mixed feelings, I really do. Make a decision that's based on your interests and needs, and try not to worry about the former T. She will have her own support system, and she went into this career knowing that she needed to be responsible for her actions.
