A wise person once told me, Let your friends do what they want to do, then you'll see what they'd rather do." that'll answer all the questions you have.

Remember, teens... you can't control the actions, behaviors, or choices of your friends (or anyone else for that matter). NEVER. So try not to waste precious time or energy trying to convince them to act a certain way or be the type of friend you want or need them to be. Instead, let them be who they are. That's when you'll know if they truly are a friend and whether you should grace them with your wonderful friendship.
