Yes, proactive is good! I still can't believe this has happened to me either but I'm no longer frozen.
I think if you're still not sure whether to expose or not just stay quiet for awhile longer - your H is probably worried sick over what you'll do - he just won't admit it.
My H finally poked his head out and emailed me Wed. I'm back on my thread now trying to sort things out. Stop by if you get a chance.
Stay strong!
