As you know I'm going through this at the moment and yes, time does help, but you need to supplement it with lots of techniques to keep the OM, and what your W is doing at any given time, off your mind. I visualize a giant stop sign whenever such thoughts starts to appear an then I visualize something positive (usually my D8 laughing). The pain is still there and it makes me feel like this will now be more difficult to resolve positively because now, she has to get over him and nothing I do now has much of an impact because she's still on a high. In the case of your W, she might not be emotionally involved. It might just be a fling which, IMO is easier to get over. In any event, Like Denver and ACC said. Give yourself some time to process things. Don't react to it in your present state. If you still want to save your family, as I do, think of the final positive outcome and that will make it all worthwhile and help you through the tough times.
Take care of yourself mate!
