Sit him down and tell him, " I know you cheated on me."
He will deny it.
Look him in the eye,and tell him again. "I KNOW you cheated on me. This isn't a question. I KNOW."
Don't tell him when,where,who,or how you know. Any information you give him tells him exactly what you know,therefore he will only admit to exactly what you know. There may be other times places, and women. You will need the entire truth.
He will ask how you know. Tell him that's none of his business, and not up for discussion. This isn't a court of law. You don't have to prove to him that you know what you know. He knows he's cheated. You don't have to convince him of it.
If you tell him how you found out, he will flip this around to it being your fault. You spyed on him. You invaded his privacy. Which is completely ridiculous, but a common wayward tactic.
If he refuses to tell you,then you can tell him you had hoped he would be open and honest, so you could then discuss the terms of attempting reconciliation. But since he's going to continue to lie,and disrespect you,you will be forced to consider your options. Then 180 him. Stop having sex. Stop cooking for him. Stop doing his laundry. Stop being his friend. Stop acting like a wife. Treat him like an annoying roomate. Be polite,but not loving. See an attorney, to find out what divorcing him looks like.Eventually he will break down and admit it. Or,not. If he doesnt,then you do need to consider if you're truly ok staying with a man who lies to you,risked your life,and has no respect for you.
Also..if they want to cheat,they find a way. He could be talking yo women online. Or maybe he leaves work early. Mine was never late from work. He was always home when he was supposed to be. He was having the affair at work, and they were having sex in her car,during dinner break.
