Oh Draco, I think your mother will only understand if you tell that either she accepts you as you are, gay and happy - or she can move to a charming little cottage (which I am sure the Malfoys still have) and live there alone until she comes to her senses. Draco is 27 that is HIGH time to grow up :)

I am glad that Harry is willing to be with Draco, he deserves happiness and someone to dote on him.
