Your husband cheated because he wanted to cheat, not because of anything you did or did not do. When he found that you knew, he unloaded all the excuses he had been making for himself. He created those to convince himself that he was right. And he just used them to deflect your seeing what he is. Don't let him do that to you. Tell him "Fuck you" just before "Good bye". @crystalt70 said it so well!

A cheater doesn't need a reson to cheat, but he/she will grasp at anything to justify his/her actions. Don't fall for it. My ex did the exact same thing. They need to make themselves feel better about what they did, so they feel no guilt. Do NOT let him blame you for HIS actions. We are responsible for ourselves and nobody else can make us do something that we don't want to do.
