Ginger knows about this. It's incumbent upon Ginger to provide a safe space for Little G to process this, and getting professional help is perfect. Great idea.
My son's godfather, grandmother and step granddad as well as exh's bff all knew about it. I can let BFF off the hook= he has no moral obligation to my son. I can even let the godfather off the hook - not everyone takes that responsibility seriously. But the grandparents? no. they both had a moral obligation to my SON not ME. MY SON who carried this with him.
Ginger has a moral obligation to little G, not wife #2.
Ginger also has to co-parent with this guy for minimally another four years and ideally the rest of little G's life, certainly through the college years. How Ginger handles this with her exh will forever change their co-parenting of Little G. Little G is the priority as is safeguarding her and their co-parenting relationship.
