if your friend doesn't care about your well-being, then he is not a real friend. it's too vague to answer really, if the thing you are being pushed to is something you can have complete control over then I'd say confront him on it. otherwise, simply say that you don't want to go in that direction, and there is no debating about it either, then ask him to never bring it up again. remember, life is too short and precious to be wasted on bad decisions.
