I talked to my W on the phone (less confrontational for her) about waking me up in the middle of the night. I told her she ripped the pillow right from under me. She said is it was dark and that I had all the bed. Of course I did I answered back you don't come to bed, I'm going to make myself comfortable.
The point of the conversation was to let her know what she's doing. She needs to be accountable for her own actions. If she goes to bed late - I'll be sleeping like a log.
