Well, I dont want to offend but she sounds like a vidictive bitch to me & you're best rid of her.

She sounds a bit crazy to me.

Take it like a man, if you are a man. Get a new email? I don't know to be honest. I'm kinda crazy and mentally unstable at the moment.

Anytime you end a relationship with someone, you should first safeguard any accounts of any kind that they might have access to. Screwing up people's accounts is SOP (standard operating procedure) for the type of person you describe and very often for anyone who has been broken up with. It's just the way it happens.
