4) Decide to make it work. One of the best things you can do to relieve the pain of a cheating spouse is make a conscious decision to work things out between the two of you. The actual act of making a decision helps a little on its own. When you begin taking actions to allow the person you love back into your life you'll begin to feel better almost immediately. It will still hurt that your spouse cheated on you but the pain will no longer consume you.
