Crazy Ex Boyfriend. I need Major Advice.?

You see, I broke up wih my 1 year boyfriend about two months ago and it has been a living hell. I have moved on and im in another relationship. My ex hasnt taken it very well and trying to pull a bunch of skeems to make it seem like my current boyfriend is cheating on me, yet there is no proof. Finally he made up a myspace of a girl who claims to be the girl that got my boyfriend to cheat on me. Yet her profile is completely fake.She is adding people she doesnt even know and telling them about me andtelling them im getting cheated on. etc.. (i know long story) well im almost positve by the way they both type that my ex boyfriend created the account to get me to believe im getting cheated on. What can I do he is ruining my life and I want to find proof that she is not real. WHAT DO I DO?!?!
