I think I can stop this.... can you help me?

W went out last night. I asked nothing. When I got home today from work I got cornered into another conversation with her. I said as little as possible. She did mention that she has noticed changes in the way I behave lately. She asked about thanksgiving. We are invited to both family's. We had been planning on going to mine, and then to hers for Christmas. She told me that she wanted to go to her uncles for thanksgiving. I told her I wanted to stick to the original plan and take our son to my family's house. I didn't mention her coming or not. She asked if it would be weird if I showed up and she wasn't there. I just said no not at all, why would it be?
I kinda got another verbal thrashing as she led the conversation towards what is going on with us right now. I just said I have told you how I felt and haven't changed my mind. Then I had to listen to her go on for half an hour about how I could never change and I was an evil person. I didn't argue or defend myself.
