I am sorry to hear about you "T". It sounds like she might have a mental disorder. Bi=polar comes to mind. We all have issues but there is no excuse for her to treat you like this.

Unfortunately, she needs help and she needs to visit her doctor to control her mood swings and you can continue with your relationship. SOmetimes, something drastic happens, and something in your brain basically becomes unbalance...

Let her talk to her physician and once medication is prescribe...she will be back to normal.
