I remember your wife being horribly afraid that you'd expose her affair to her family. Who still doesn't know at this point?

Is her OM married, and does his wife know?

What's the financial situation? I just re-read some of your old posts, and remember you saying how your wife was running up the bills buying new clothes and stuff, even though she's not bringing in much income. That needs to stop immediately, if you haven't already done so.
