Alright, I have these two close bros of mine. One of them simply acts like a dick to me all the time, but when we are alone, he is respectful and great to be around.

In front of others, he ridicules me in every shape and form, from my BJJ to the uniform I wear at work to the girls I have been rejected by in the past. He calls me fat etc even though I have a lower body fat than him. I realise we are in high school and he will be insignificant when we leave, but I liked who he was before he acted like this. I simply do not reply with anything other than agree and amplify, but with a facial expression and tone of voice suggesting that I really can't be bothered with his shit.

All I can think about is one of the Laws of Power, the one about keeping your enemies closer than your friends. I have been improving my SMV and my Game, could he simply be jealous?

What do you do if one of your very close friends of several years does this?
