Enabling behavior is something we do because of love. It's only natural to want to help our loved ones; however, when it comes to some things, helping is like throwing fuel on a fire.
To enable is to make things possible. It is supplying the means, knowledge, or opportunity to be or do something.
In it's true form, enabling behavior is a positive thing. It is human instinct to reach out and help someone we love when they are down or having problems. However, when we apply it to behavior and things such as addiction, financial trouble due to poor choices, and codependency, enabling behaviors have the reverse effect of what is intended.
Some examples are-
Repeatedly bailing them out of jail, financial problems, or other "problems" they get themselves into
Giving them "one more chance" - ...over and over again
Ignoring the problem - because they get defensive when you bring it up or you hope that it will magically go away
Joining them in the behavior when you know it's a problem for them - drinking, gambling, etc
Joining them in blaming others for their feelings and/or problems
Accepting their excuses and rationalizations - "I'm destroying myself with alcohol because I'm depressed."
Keeping the peace; believing a lack of conflict will help
Doing for them what they should do for themselves
Softening or removing the consequences of their behavior
Repeatedly coming to the "Rescue"
