It sounds to me like you're a little bored and indulging in some "what if" fantasy. Can you get away without your children? If you can take some time and play tourist, even if it is in your own town. Do all the things people who do not live in the area do. Do things you wouldn't normally do. Go out to eat. Get a room. Spend the night. Add something different to your life to break the monotony. After you do this once, do it again. Keep yourself discovering each other and keep your relationship alive.
