I think you might be right SE. Other people have told me that they are all over each other like a rash and are worse than any teenagers (yuck!). I had to smile when i read about your H being on phone while supposedly with the kids. Before I realised that this A could be serious I kept finding me back door unlocked and yet nobody (ie the kids) would own up to going into the garden. This was during the winter and so they had no need to go out there. One day I went through the usual routine of asking them and then D16 told me that her dad kept going out to the shed when he was with them! It suddenly dawned on me that he was going in there to either TM or phone OW back! So I cured that by buying the biggest padlock I could find and I did not put the key with all the others. We have a cellar which locks too and is only accessible from the garden so I locked that. Let's just say that is has never been mentioned since (when I first asked him about this he denied going in the shed) and he certainly hasn't asked me where the key is! Now however that OW is common knowledge to us all he blatantly answers the phone to her with us in the room. He does go out of the room to speak to her but it obviously her b/c I can hear her voice and I far as I know he doesn't know many women with an eastern european accent!
