Mother had an affair. They do not know. I won’t tell them but would prefer mother did.
It’s relatively civil and there won’t be a custody fight. We at least agree they come first.
Why do you want your kids to know their mother had an affair? My exDH did a bunch of extremely crappy things in our marriage, some so awful I was embarrassed to tell anyone, so I ended up initiating a divorce. I've never told my kids any of that stuff, nor will I. You kids don't need to feel like they need to take sides in your divorce or like they are betraying you by still loving their mom as much as they did before. I guarantee you telling them will make this process more traumatic for them. If when they are fully independent adults you still feel the need to tell them, revisit the pros and cons.
