Here's my perspective on letting go. If you "Let go" and still obsess, worry, stress, fret, panic, throw up or snoop, you haven't really let go. Letting go will feel almost like indifference; regardless of what she does, you're going to do your own thing, what's best for you and your kids. Sure you'll stress over small details, about custody arrangements and finances, but over losing your W? Nope. Let go.
