Throwaway! The credible threat of violence is useful and is certainly a skill to teach your sons.

Personal anecdata! My wife messed around once. We had young children who needed a mom and a non-broken home. I calmly visited the home of the other man. I told him that if my wife divorced me that was her choice and I would not stand in their way. I told him that if my wife did not divorce me and he continued to see her then I would beat the hell out of him. I left. Things turned out well for my children, over 5 years later, in that their parents remain married because the other dude stopped speaking to my wife.
