It's imperative. I've never seen anyone successfully affair-bust or Divorce-bust without a really good GAL plan. It builds your own self-confidence, and it re-attracts your spouse, and it has the side benefit that if your spouse DOESN'T come to their senses, you're then all that much more emotionally and physically healthy for the next guy!
