“What can I say if you are missing the sensitivity bone?”
I am not sure that we are the ones who are missing something here. It is obvious from your posts and your attitude toward this subject that this is something that happened to you. If that is the case, you can hardly be deemed impartial, and you are letting your feelings of being let down get in the way. I hope that you will be able to get over this soon, because if the guy is married to your friend, this is not a situation that will go away anytime soon. The sooner you get over it the better off you will be.
