WAW w/Exit Affair or WW? - Don't Want Divorce (2)

[BL42]

I'm considering having a conversation with my W regarding the kids and OM2 staying overnight when they're there and having breakfast together. I doubt she'll change her behavior but it seems wrong to let it go unaddressed as if nothing is going on, with D2 mentioning him and S5 telling my mom about him and seemingly unsettled. It feels like a situation where a dad should stand up for what's right for his kids.

This is honestly not a ploy to have an R talk, it's solely related to the kids best interests - I don't see why any extra curriculars can't go on without them around until down the road.

I have a feeling what people here will say, but...thoughts?
