I did the same thing man, and you should not feel ashamed. You told her the truth (if you did/do indeed love her) and if she pushed you away then screw her. I was upset at first too, but as I thought about it (NC helped with this), you can't treat some one as a priority if they only treat you as an option. If she calls you saying "I messed up, I thought about it and you're the only one for me, please take me back." then think about it. If not, move on.
I still love the object of my NC, prob always will, but you can't make someone love you, just let her go with love and get on with your life.
