Can a marriage be saved if one spouse is emotionally dead?

That all depends on your point of view. If you feel a marriage is a loving relationship where two people share their lives, make love, have fun, have intimate romantic dinners and things like this, then the answer is no. If marriage to you is more like a business relationship where you see each other occaisionally, speak very little, share expenses and have little or no romantic involvement; then of course an emotionally dead marriage should work fine. It just depends on how your willing to live the rest of your life.
