If you begged your ex to come back but she said she can't look back and just wants to be friends and you accepted it how do you get over her and should you be her friend and hang on to a bit of hope?

Find someone who will treat you right and who is worthy of your attention. Ask yourself if you think you will EVER be able to trust her again.

Find peace in yourself. Learn to love you insted of another. Be friends, but don't hope and dream of renewing love lost. Make yourself a better person for you. Take it one day at a time.
