You deserve someone who wants to be with you. Right now, you are his "backup". He will keep searching for something he can never find. His putting people on pedestals is a defense mechanism. When they turn out to be simply human, he has an excuse to leave the relationship. Has he ever married? If not, at this point in his life, I can tell you he never will.

At any rate, I hope you can stop obsessing over him. His charm is only skin deep. Look for that peace you have when he's gone,and make it permanent.
