"ok, so if he is cheating again this is it, he goes, I only loose a liar and I can be happy on my own". Knowing that you will be ok if he leaves will help you stop freeting, I know my H's life would be a mess if we were to divorce, he'd have bigger internal issues in his hands, I, on the other hand, will have the peace and knowledge that I gave it my all and that I can be happy with my kids--of course I'd be sad and it'd be hard, but I won't be a wreck, I'd have no regrets.
