8. Your self-esteem is negatively affected.
Period. Dot. The. End.
If ANY of these reasons contribute to your self-esteem withering away whenever you are around this friend, it is absolutely time to break up. Your self-esteem has enough to deal with! We have to maintain our grades, our jobs, our apartments, our relationships, and all the while we are fighting off self-doubt every step of the way. Friends are supposed to be our cheerleaders, our support systems, our buds. If for any reason a friend DOES NOT contribute to your overall confidence, then it’s really not a friendship at all.
