IT sounds to me like you are experiencing some anxiety and/or depression. Take my work for it, if you are no treated for this it will probably tear you and your relationship apart. My husband is depressed and refuses to do anything about it, and we are hanging on by a thread. Things have been much worse for us and we are working on it, but it is by no means "blissful". I strongly suggest that you see a professional that can get to the root of this and help you find a way to deal with it.
