If you love him learn to understand him and let him process his own way until he is ready to change it. He'll eventually learn that things are not working the way he is dealing with them and then he will start things himself.

There's no point getting into an argument (which you know will happen), because you feel lonely. Something happens to some people when they get into reationships; They say they love the person they're with, then they try to change that person. Learn to deal with things the way they are and concentrate and develop your own coping tools & stratgies go to therapy if you need to who knows you may even learn some tips there on how to deal with the situtaion?

Also have you thought that he may be avoidant personality and addicted to computer games?
