Healthy people seldom engage in friendships that are more work than necessary, and have little or no problem cutting ties when a friendship becomes over-taxing, overly demanding or draining. Friendship is supposed to be enjoyable. Thus, whenever any of the following occur in a friendship, I’d suggest it is time to cut and run. I am not at all suggesting the friendship ONLY involves good times. I am suggesting that if a friendship is hard work when it is time for the good times (no present illness, no unusual trauma) then it might be time to move on:

Your friend: (1) Doesn’t want you to have other friends; expresses jealousy through sullenness, withdrawal or antagonism.
(2) Lies to you, about you, or about others.
(3) Expects you to keep “special” secrets or information when the knowledge makes you uncomfortable.
(4) Watches the clock if you are late and interprets your lateness as meaning something about the friendship.
(5) Compares your behavior in one friendship with your behavior in another (“How come you are never this way with your other friends?”).
(6) Expects you to buy into his or her values even when they differ from your values.
(7) Wants or needs to book up your time a long time in advance to make sure your life is planned around his or her life.
(8) Plays games of “hide and seek” to see how much you care or how important the friendship is to you.
