After ending a abusive, controlling 3yr relationship, its been 2 weeks and she wants to know if we can be friends. She still blames me for our relationship not working out, but I told her no way do I want to be friends, its over and time to move on. Is being friends a good or bad ideal? And why won't she stay out of my life?

Being "just friends" with someone after a break-up rarely works. If she was an abusive and controlling partner then she would probably be an abusive and controlling friend.
You made the right choice telling her its over and time to move on, stick with it.
She probably won't accept this for a while as she may still have feelings for you, just stand your ground and eventually this will pass.
