U were betrayed by ur friends? Then why do u them call them ur 'friends'. U will end up being cheated by them again and again. Move on and find some real friends who have a good-heart. I mean if they betray, they are using u. It sounds really hard and rude to say this, i didn't mean to be so. But sometimes we have to be more clever than being good to them in a situation like this. Dont let urself in a situation like this. It's high time u understand 'how ur friends actually are?' In a way this will help u in future in how to make good friends. Its just an accident, try to forget it and focus on ur life, be happy, its ur life, they have nothing to do it. And they are no-one to betray u, unless they have a reason. Go and ask them why they did so,if they owe you a lame reason, then move on. But if u understand what mistake of u they were trying to make u realise, then its upto u to decide, apologise to them and renew ur friendship. Because friendship is more precious to life.
