5. Get into contact with OWH... keep that line open.. call him every day and trade notes. It's better if H doesn't know, but if he finds out its not the end of the world.
6. Keep goin to karate class, it should help you relieve some stress.
7. Keep close to your kids, he may try to turn them against you too. Stick close to all the family... right now he's going to try to put a RIFT between YOU and his family and friends...
8. The fact that he didn't mention the affair to them at all... not surprising... he didn't have any cards to play there. I wonder why though your In laws never ASKED him about it? Why didn't they ask him why he's been lying to everyone?
9. Don't let your phone or your pc out of your sight.
OWH needs to know how to combat an affair too... MWD's book isn't too helpful there... he may try being nice too... He will need a crash course from you.
