This is one of the main reasons why if you have children, a young daughter especially, you have to be there for your kids. Your wife may think she can do better than you, but when she realises that no men will commit to her, just fuck her, she'll get desperate. And that is the perfect situation for sick paedophiles, who will infiltrate the family under the guise of the new husband, and prey on the children. All the wives eventually realise, and this one is no exception, but they choose to turn a blind eye to it or deny it entirely, if it means loosing their "husband"/"boy friend", and being alone again.
