I read somewhere that it's sort of like a 'knight in shining armor' philosophy. OP needs "rescuing" and the WAS thinks they're the person for the job. OP is someone who needs help. They help the LBS feel empowered and needed. The OP makes LBS feel better about themselves.
I don't know if that's what hooked my H, but OW in my sitch was definitely dysfunctional, too.
