joie, what a mess!!! I can certainly see why your H would feel the need to keep on the good side of OW (and she knows this too! I don't like her). She could ruin your H (and you) financially. I think this is a situation where you do need to stand by your H, get him through this, and then see where his heart is afterwards. He is thinking of your future, trying to keep OW at bay...
