When ex-T abandoned me, I still had hope she would take me back. I finally realized I could never trust her again. Also, in the beginning, I thought I could get closure from her. I realized again that I could never trust her words. She always told me actions speak louder than words, and her actions were screaming at me. I'm now happy she didn't take me back. I don't want someone like her in my life.

Are you looking for closure? That would be different than seeking her for treatment. Could you ever trust her words or actions again? My guess is you'll probably constantly fear being terminated.
