Best Friend question please answer - my best friend met a new friend ?

i have known my best Friend for a little over 7 years now and we have been best friends and now he met someone that i really never liked and every time we go to hang out the new kid always has to come i really don't like him and every time i tell my Friend not to bring him he says that hes a friend and does not want to ditch him .. what do i do?? do i tell him its either me or him?

Tell him that you want to hang out with him without that other guy and if he is really unable to do that, then maybe he wants to just not have friends outside of that one guy.Basically, your best friend is being a dick and you either need a new best friend, or he needs to stop being so clingy to that other guy.
