Phew that is quite a story @mike_m . In my opinion she is not well and needs regular therapy. I'm not sure about the meds she's on but she would ideally do therapy as well as taking them so that the therapist can see if they're working. Meds cannot help her alone.

In my experience, this falling in and out of love is normal in a long term relationship and/or a breakup but you don't usually go updating your partner/ex every time your feelings change. She may need some more time to process her feelings so that she can make a decision.
