So one of my best friends is getting married and im not a fan of his girl, Ive managed to drop enough hints that im not excited about this to get out of being best man and having to lie in speeches. However i had to agree to be a croomsman.

How do i handle this and be a good friend, surely a good friend would be honest and like 'are you sure you want this dude?' or would that make me a bad friend.

im confused.
