My Friend Got Cheated On And Knocked Out! How do i help him?

Don't bring it up in front of him. You don't want him to feel any more insecure, do you? Take him out to have a good time, ball games, dinner, parties maybe.. Make him feel good about himself, maybe even take him to get some new clothes..? Be nice around him. I'm sorry to hear he got knocked out too, I hope he recovers soon :) Best of luck, -msar27
