Have you sat down w/her and explained the situation about the garage door and alarm on the days you have to go to work? You could say something like: "wife, is there any way that you can come in earlier during the week? The reason that I am asking is that I have to get up at 5:00 am to go to work and when the garage door and alarm make noise, they disturb my sleep and I can't go back to sleep for the 2 hours, which they affects my work performance. Any assistance from you on this matter is greatly appreciated."
If you speak to her about this, you will need to be calm and keep your voice as even as possible.
Not yet. All bets point to her asking me to leave the house of that's the case. I can try though.
