I believe you need to talk her about this and leave her on good note because its hurting you also too much
sounds fair to me.
i like this answer, and.. works well.
Yea... It sounds the best possible action he can take. Well... If you REALLY into her, I think you'll do anything for her. BUT, if she still see her ex the way she did. Leave her. Unless you're masochist, don't continue that relationship.
