I have to agree - you know he wants a divorce, you know he is now in the "paperwork" stage, you know about OW and the baby... just read it and be done with it.
Be aware - your H will try and butter you up so the divorce will go how he wants it (no contesting, no attnys and so on). Do not bend on your stance that you will be retaining your own counsel and BE SURE to get the money he owes you. No excuses!
