You can't stop your WW from lying to y'all son. She's going to be looking for sympathy where ever she can get it. Even if it's your son.
But you have to not lie to him, because that would really hurt him. He's not dumb and now he knows what's going on. Do you think his current school is a healthy place for him at the moment?
I would get him line to start speaking with a certified person. He has feelings in all this as well and will need to get them out.
Don't lie to him or try to push aside his feelings and be there for him. He will most likely start attaching himself too you. Make as much time for him as possible. And listen and validate his feelings.
