Seems to me like he needs an new aversion.  Time to use your womanly charm  to lure him away from the tube and into your bedroom.  Don't worry about what you think he is doing.  Think of ways that will make him more alluring  and attractive to you.  It can be enjoyable for you as well.  No need to fight, accuse or argue.  Think of positive ways to get his attention and away from the computer.   As the expression goes " you catch more bees with honey than you do with vinegar! Good luck! wwwsecondmarriagesucesscom
