glad you had a laugh....laughing is a life-saver. Yes, it's amazing that they don't understand they're caught up in much the same response as a drug addict...I mentioned this to my H once and REALLY made him mad! he wanted to see the research to back up my claim...actually I have it, but I kind of let it go, seemed like a cheeseless tunnel. I'd be careful about the letter, my experience is that OW is every bit as able to justify what they're doing as is H, and you don't want to add fuel to her fire....However, writing it could be very helpful to you personally. I'd sure post it here before I sent it though.
