I'm a big believer in some personal autonomy. I don't feel I owe it to my husband to share every one of my deepest and darkest secrets. And I don't push him to tell me everything on his mind either. God no, I don't want to know everything on his mind. I'm a gal who enjoys a bit of mystery and his over-sharing would be a buzz kill. But there is a difference between "thought" and "action". It's fine to fantasize -- no harm is done.
