Inigo doesn't care how supposedly good it is, it can't be good enough to replace an entire friendship, surely! (Except that he isn't really offended at all, he's just dramatically going along with all of this. Look at his mock offense! It's so good, it's practically practised.)

"I'm hurt. I'm so hurt! I think I might just throw myself straight out into the sea after all!"
