I don't really think there is an appropriate response other than if you here bad things about the OM that could be harmful then get a lawyer.
I just think it can be confusing for your children to see their parents with someone else so soon. It's not that I think this OM is a criminal or something. But it jut confuses son when there is already enough confusion in his life.
I look at this way, if W wants to put my son through that then that's not who I want to be married to and I will move in another direction.
I will still be cordial and co parent with her, but I will do things differently.
In the end I think we have to accept that we don't have control over te situation. All we can do is voice out concerns to our W and hope they have enough respect left to honor those concerns.
As I have told my wife. "I can't control what you decide to do in the end, but I can and will try to do what's best for my son"
