I have not watched the movie.

"She didn't start officially dating the ex-bf until after the divorce was final."

Because it was not a PA she claims not cheating. Living in the land of denial.

Well she was having an EA while married. Lining up a future replacement to be ready to replace her H before she left him.

Still cheating, still justifying an affair.

Instead of using her energy to get the next mr perfect one can only guess what the outcome would of been if this same energy was used to repair her marriage.

Never attempting to save the M diffinitly reduces the odds for success.

She lost the moral high ground by having an EA before the D.
