I know you've read my posts and know about my sleeplessness and nightmares. I have truly come to believe, as Beatrice and others suggested, that it is my subconscious cleaning house. Everynight, some unpleasant dream in which X has a starring role, and waking up startled. As an Army wife, I am very comfortable alone, and do not feel scared or threatened, nor do I feel the need of a male presence.
Perhaps you, like I myself, are just going through a 'mental house cleansing, and it's something we have to go through, whether we like it or not. I liken it to the movie "Shawshank Redemption" and climbing through "four football fields of unbelievable filth to freedom" Unpleasant, but necessary.
