Am I truely a bad man for being honest to my wife about cheating on her with her sister?

I'd like to appologize to all the women of the world and my wife, what i did was truely embarring and a truely low moment for me. Even though she dumped me and threw things at me I still love her and I know in her heart she loves me too. I want to become a better man, is there still hope for me? I see the error of my ways and let the alcohol get the best of me for one night. Please if you have nothing nice to say don't say it as I am getting bombarded with all these nasty posts and it hurts to know other people could be so cruel as we all are human and we all make mistakes.
