What is sad is that Favre never had to go through the public scrutiny that Big Ben has this last year, and I'm sure his behavior in Wisconsin night clubs was no better. It was all covered up.
As for the family stuff, I have zero empathy for Deanna. Any woman that knows about this behavior and "puts up" with it needs no sympathy. She is not an extraordinary person for being forgiving. She has a very prestigious role in life as Mrs. Brett Favre and she needs for nothing. Basically she's made a trade off: materialism over character.
Marriage is simple, you are either faithful or not. If you want to do everything that moves, stay single. When you make your committment, mean it.
