Poisonous people do not deserve your time. To think otherwise is masochistic. The best way to approach a potential break is simple: Confide in them honestly but tactfully and explain your concerns. If they bite back, your conclusions have been confirmed. Drop them like any other bad habit. If they promise to change, first spend at least two weeks apart to develop other positive influences in your life and diminish psychological dependency. The next trial period should have a set duration and consist of pass-or-fail criteria. If this approach is too confrontational for you, just politely refuse to interact with them. Be in the middle of something when the call comes, and have a prior commitment when the invitation to hang out comes. Once you see the benefits of decreased time with these people, it will be easier to stop communication altogether.
