The Codependent: This lady cannot be alone. EVER. She cannot feel complete without another person by her side. If she doesn't have HIM, she will turn to someone or something else to fill the void; drugs, alcohol, shopping, eating, or even you -- her single female friend.
The Guy She Wants Pushing Her Emotional Wheelchair: Someone who needs her just as much as she needs him. Surprise! He can't be alone either. A match made in hell. They'll lovingly refer to themselves as "we." They'll call themselves "inseparable" and you'll wonder what happened to their individual identities.
Her Wheelchair Needs: To work through her co-dependency issues and learn how to cope with life on her own. To develop her own identity before merging with her "other half."
