Did I read somewhere that you and H watched a movie and he was on the Blackberry the entire time? No need to smash anything against a wall but I am curious why you allowed it to continue?

Why not say "H, I am trying to watch a movie and your constant use of the Blackberry is rude and distracting. Please go play with your phone somewhere else so I can enjoy the movie"

Honestly, what do you think he is doing on there? Affairs are addictive situations, so much so that his son and W will come second if OW is available to chat.
