It's funny. I'm not entirely sure why she did this but when I was away on business last week and she checked in on the house, she turned the heat down to 66 deg. That is normally where she would put it. I mean she hasn't lived there in over two months and she is going to divorce me and she still turned the heat down. Go figure. I was really upset today about the state of things. That combined with a few glasses of whiskey prompted me to give her a short text about the thermostat. I got no reply. I am going to stop initiating contact I guess. Thanks Grocerykartman for sticking with my post and to all others for their advice.
