Jude Law's performance in Alfie made me smile, and his portrayal of a wounded solider in Cold Mountain pulled my heartstrings. But his latest act - cheating on his fiancé, Sienna Miller, with his children's nanny - has left a bitter taste in my mouth.

It's an ongoing joke about what part of the anatomy a man thinks with. We laugh that it's a "man thing," right? But with the decline in morals, a skyrocketing divorce rate and an increasing decay of family, how can we make light of it?

Cheating with the babysitter - another age-old joke. It was even reported that Jude's children were present and at least one of them witnessed the infidelity. Not only was Jude breaking the trust and a commitment to his fiancé, but also to his kids. His careless actions may have implanted the idea that unfaithfulness and dishonesty are OK in his children's impressionable minds. Kids learn how to behave and what is right and wrong by watching their greatest role models: their parents. That's what should have been on the forefront of Jude's mind, not Daisy Wright. But for too many men, raising their children with values and putting them above everything gets outranked by the need to satisfy their own selfish needs.

As someone who has been cheated on in a marriage, I know first-hand that the pain inflicted on all parties is immeasurable. Jude and Sienna may not have worn the gold bands on their fingers yet, but to get to the point where you decide this is the one, forever, some level of trust already must be there. What has happened to trust? Trust that a husband, boyfriend or fiancé will be faithful? Trust that a father will put his children's best interests before anything else? If I were the mother of his children (Sadie Frost), I would be livid!

Don't get me wrong, I do believe there are many good men out there - good fathers, good husbands. But as a society, we tend to put the Jude Laws on pedestals, not the dads who work 10 hours then come home and give baths, hugs and kisses, read stories and love and respect their wives and fiancés. Those are the men who need to honored and celebrated.

In a statement, Jude said, "There is no defense for my actions, which I deeply regret, and I ask that you respect our privacy at this very difficult time." I agree there's no defense, but I hope he gets the same privacy his kids will get one day when they're asked about their father's escapades. If he had thought for just a second about how his actions would affect his children, maybe he would have just driven the nanny home.
