trying to be patient and strong

For now, I would reply to him:

"Thank you for being clear about what your intentions are. I would still insist that you don't expose the children to your girlfriend while we are still married, and I hope you'll strongly consider that, FOR THE SAKE OF THE KIDS. I can assure you, what we each do with them is still -- and will forever remain -- BOTH of our "business," as their parents. The fact that you don't see the inappropriateness of it, FOR THEM, speaks volumes about your decision-making right now. Please reconsider. Karen"

Perfect!

But this one is pretty Fing good too!

I would be more direct in my responce. Probably something like F-u ya' tool!
