It's really hard when your H gives insincere responses by saying what he thinks he should say, rather than what he really feels......although now things are more out in the open perhaps that will change.
However, a typical DB response is to tell you to look at his behaviour rather than what he says.
You don't think any of your children fancy giving OW's H and family the info on what's going on? just a thought. It would stop OW being able to keep it cool and living the best of both worlds.
On the other hand, maybe she is playing it cool and is so chilled because she is not as invested in the R with your H as he thinks he is....maybe she is just having a bit of fun with your H?
