I don't think the ex boyfriend was 'normal' he knew she was a bigamist fantasist yet maintained a realtionship with her, even after she pretended her sister had died of an overdose. His standards in relationships are therefore pretty warped.
I thought it was very sad for the husbands, they seem to really beleive that they had found some special romatic love with her, so wne along with the whirlwind reltionship only to have their lives then fall apart before thier eyes. They seemed quite vulnerable men that she had obviously purposely targetted, most rationale worldly wise men would have avoided her like the plague.
She is obviously mentally ill.
I agree many people do live in quite distorted realies, where they are perpetually at the centre of a drama and the truth is a murky unclear concept to them, but she was a very dangerous extreme version of this.
I missed thr last 15mins, what happened to her in the end? did she break up with wayne?
