So there is a show on Netflix called Fire Fly where a woman was having an affair on her husband. The husband wasn’t a horrible guy but had certainly neglected her. She would say she was going out for groceries at night etc. So one night he met her at the porch and simply said “ I know what you are up to but you can’t have both. You need to make a decision. “ Short simple but yet powerful.

Yep I agree you go dark it’s more of the same and your marriage probably won’t improve. I also know that while she is having an affair your marriage won’t improve. So the question becomes what do you want to do.
