Theguy, I can't quite remember your history with her, sorry. She left you for another guy? Or maybe I'm confusing you with another poster. You might need to give us some more backstory or a cliff notes reminder of what happened.
Also, are you her doctor? Why are you diagnosing her? It's ok to suspect that she has some kind of emotional problem, but until a doctor confirms this, I'm not sure it's wise to be slapping a medical label on her problem.
