Uh-oh, this may sound familiar: University of Houston researcher Chip Knee has discovered that sometimes people place too much emotional weight on their relationships, which is unhealthy. Psychologists call it relationship-contingent self-esteem (RCSE). Knee says: "An overwhelming amount of the wrong kind of commitment can actually undermine a relationship. When something happens in a relationship, these individuals don't separate themselves from it. They immediately feel personally connected to any negative circumstance in a relationship and become anxious, more depressed and hostile." Sigh. Raise your hand if you've been there.
