Everything I'm putting here is from the book, Codependency No More by Melody Beattie.
Although two codependents might disagree on the definition of codependency, if they discuss the issues with each other, each will probably sense what the other person means. They will share ideas about things they have in common--things they do, think, feel and say--that are characteristic of codependency. It is on these points--symptoms, problems, coping mechanism, or reactions--that most definitions and recovery programs overlap and agree. These points dictate recovery. They are the things we need to recognize, accept, live with, deal with, struggle through, and frequently change.
Before I list the things codependents tend to do, however, I will make an important point: Having these problems does not mean we're bad, defective or inferior. Some of us learned these behaviors as children. Other people learned them later in life. We have learned some of these things from our own interpretation of religion. Some women were taught these behaviors were desirable feminine attributes. Wherever we learned to do these things, most of us learned our lessons well.
Most of us started doing these things out of necessity to protect ourselves and meet our needs. We performed, felt and thought these things to survive--emotionally, mentally, and sometimes physically. We tried to cope with our complex worlds in the best ways. It is not always easy to live with normal, healthy people. It is particularly difficult to live with sick, disturbed or troubled people. It is horrible having to live with a raving alcoholic. Many of us have been trying to cope with outrageous circumstances and these efforts have been both admirable and heroic. We have done the best we could.

The following checklist is long but not all-inclusive. Like other people, codependents do, feel, and think many things. There are not a certain number of traits that guarantees whether a person is or isn't codependent. Each person is different; each person has his or her way of doing things. I'm just trying to paint a picture. The interpretation, or decision, is up to you. What's most important is that you first identify behaviors or areas that cause you problems and then decide what to do.

The activity at the end of the chapter says to go through the checklist and mark each characteristic with a 0 if it is never a problem for you, mark the characteristic with a 1 if it is occasionally a problem and mark it with a 2 if it is frequently a problem. It doesn't tell you to add them or how to quantify whether or not you are codependent but to merely use them to establish goals for yourself in the future. The idea is to respond to each problem area individually and find ways to be healthier.
