Did anyone see "Moment of Truth," and what do you think?

i saw the one with that horrible woman who admitted she was in love with her ex and that she cheated and all those terrible things! i realized i have a great marriage and i'm lucky! i have no secrets, i don't believe in secrets in a marriage. i do have things he doesn't know but it's not stuff i've gone out of my way to hide, it's just things that never really came up! i certainly hope that's not the average marriages!
