Tell Her You Love Her.
Tell Her You Will Always Be Here For Her.
Let Her Know That She Can Always Depend On You And Your Belief In Her.
Explain to her that you are tired of listening to an abuse that she is unwilling to change. Tell her not to tell you about the next girl he cheats on her with. Let her know that it is unresolvable, because she is the only one who can change the situation. However, you are tired of hearing about that which she is unable or unwilling to change. Don't forget to remind her that you are there for her and you love her unconditionally.
Every time she wants to discuss his cheating tell her firmly that as long as she is incapable of taking back her power, her self-respect, and her dignity this is an experience you are willing to do without. It is not your road to travel, it is hers until she realizes that she deserves more than better, because she is a princess and should be protected from harm and hurt.
Change the subject after giving her a hug and telling her you care and love her.
This is going to drive her crazy and consume her, because you are not willing to listen to her self-abuse and acceptance of some idiot emotionally using and abusing her.
When she is ready to leave him for good, validate her decision by letting her know that you are proud of her then go out and celebrate with her.
Don't bitch, don't complain, don't enable, don't listen, JUST LOVE HER AND BE THERE FOR HER.
