I feel like I am operating in a vacuum

[antlers]

Your happiness can't depend on whether or not your spouse comes back. You need to become detached so that your situation doesn't ruin your life. If you shift your focus to make yourself happier as a way to implement change in your relationship, or because you realize that no one else can do it for you, the message is to JUST DO IT. You are solely responsible for your happiness. Whether your spouse comes back or not, you will need to find satisfaction in your life...start now!
