To NoD..I understand why you are confused about your W behavior,why would she want to be with this guy who sounds like a jerk? Well it is easy to fall into past relationships..especially if there was not closure the first time..and also if this guy is calling her, sucking her into his life.Your W must have some unhappiness and is hoping this guy can fill it.It is a vicious, no-win cycle. There must still be some attraction..Good Luck.
