The detachment part is very hard for me too Melo. Use the anger positively to focus yourself. Remember you can't be logical with her. She is living in fantasy land and nothing you say will change that.
Channel the anger into positive action for YOU. Hit the gym, go running, drive somewhere, work on car, go hiking, whatever you gotta do.
