I have a 16 yr old son who doesn't want to do anything except play computer games or watch TV. It is very common for him not to go outside all weekend even if asked. He isn't doing well in his junior year at school and is blowing off some of his courses. To get him doing any kind of physical activity is difficult. He is very angry with us (his parents) right now because we took away his electronic privileges. So now he will get home from school, have a snack and go up to his room for the evening refusing to come downstairs for dinner. He says he won't eat dinner with his Dad. It looks like a big temper tantrum but it is not very pleasant at home right now.
As a bit of background, we have moved several times to different cities/countries due to his Dads work. Any advice on how to handle this situation and rebuild this relationship??
