I used to sleep in sweat pants and a tee, wear socks to bed, keep a backpack with my wallet and keys near the bed, along with shoes in case I needed to leave in an emergency. I kept an extra set of keys, emergency money, and extra clothes and toiletries at work in case I needed to sleep on the couch at work because alcoholic was raging and I couldn't go home.
I am separated from alcoholic ex a bit more than 6 months now. I'm glad I don't have to do this any more.
