I want to destroy my friend's marriage. I'll explain: I have a friend who is in a ridiculously failed relationship. About two years ago his wife (pretty wisely) wanted out -- she wanted more passion, more happiness -- they'd become like brother and sister, she said. But when he moved out and started seeing someone else, his wife fell into a deep depression. He ended up feeling crushed with guilt and has come back to take care of her. Now they're both miserable, but even knowing this he can't bring himself to start a new life. How do I split these two crazy kids apart?
