Re your W thinking you are on a porn site - can't you just tell her you are on DB?
Show her the site - she might be impressed that you are trying to work on the M instead of looking at 'Raunchy Rachel's' big boobies.
Hey, because this site has the word divorce in it, that might shake her up a bit and she might think 'heck, he wants to divorce me. I'd better do something to soften him!'
You never know, you might get your inhouse *miaow* then.
