W just called me at work and I couldn't answer because it hurts too much to talk to her now. She sent me a text and said son wants to talk to me.

I called and she answered, I said can I talk to son. She had the nerve to ask "what's the matter". I said can i please just talk to son. She said you were nice to me yesterday and we talked now you hate me?

I didn't give her the satisfaction of arguing. I can't do it anymore. Does she really think that I would just be accepting of her new OM and that she's having a physical R with him? What is wrong with her?
