Most don't lask, some do though and you should be prepared for that. However I think the more attention you give their relationship and focus on it with your soon to be ex-wife the dug in she will get just to show you how "wonderful" it is. Unless the OM is negatively affecting your kids, I wouldn't give him 1 second of lip service when interacting with your wife. Talk about anything other than him. Let her find out and experience his flaws. Discussing him in any manner whatsoever, will cause her to jump to his defense and make it more difficult for her to see his shortcomings.
