O.C.D.D (Obsessive Compulsive Douchebag Disorder)
You're the kind of person who can't live without a lover who is a total piece of garbage. You take them back even when they dump you, steal your money, and lie to your face.
'He dumped me, but I still took him back.'
'He stole my money, but I believed him.'
'He lied to my face, but I still believed in him.'
