Emotionally trapped and sexless

I have read so many of the threads here on this topic but every situation is different, and I need help...and advice please. Short background: my wife and I have been together for 26 years and recently I heard the "I have never been truly happy" speech. She says she was waiting for the kids to finish school before leaving...that was 3 years ago and she is still here. She is a child sexual abuse victim and over the years has occasionally shut down sexually for a few weeks. Recently, she announced that we would no longer be having sex until she feels that she has an emotionally connected relationship. She won't say how long that might take and won't say what it is she needs from me aside from patience. She says she doesnt feel loved and cherished and feels little affection for me. She says she is going to take care of herself now. I am the romantic of the two, love her with all my heart but am angry that she has blocked me out emotionally and doesn't want to work on this problem together. I read about sexless marriages and don't want to end up there as I know I can't live that way. I'm in counseling and am pouring over relationship books trying to find the right path to save my marriage. Does anyone have any advice on how to turn things around? I will be grateful for the help. Thanks,
