SD - my heart goes out to you big time. It is awful and very, very hurtful. Time to tell yourself that it is battle mode, or whatever mindset mode you want to call it so that you can focus on you. You deserve better, you are a better man than you are being treated. Now give yourself the respect you deserve by treating yourself well and not allowing her to hurt you more. Focus on you now. Have a drink with some guy friends and talk their ear off. Go workout to get the anger out. If you are in NYC, run around central park. Get some self-help books (7 habits), read them and start working on yourself.
Commit to a new you (GAL, 180s). It is the best you can do for you and your daughter.
