Tell your S to avoid listening and telling you about your W and the OM. Tell him it hurts you so much and if you are not told it won't hurt you so much.
My mother had a policy, she would say that when people talk abt me and I don't know it doesn't affect me BUT when you come to tell me you are now the one causing my pain.
Try to GAL and stop focus g on them. Focus on yourself and detach. Move her stuff to the garage and tell her she needs to behave and not involve your S in her affairs. She needs to grow up and show some respect.
