Sounds like he is 'hiding' his addiction ... playing when you're not around. That kind of thing leads to him *looking forward* to you not being around so he can play. Not really a good thing. But if you don't think there's a competition between time spent with you and time spent with the game, then I guess it's OK ... for now. But from what I know about how addictive this game is, it will start to take over again at some point; it might happen so slowly that you barely realize it until it's really bad again.

You shouldn't ever think what you're feeling isn't right. The game is just a bunch of pointless 1's and 0's in his computer. You are a real person. You don't have to bee too in-touch with life to figure out which is more important (unless the addiction has control).

If you want my professional advice pull a lorena bobbit, chop up his computer , take it for a drive and throw it out the window

In the early levels of the game - it appears to be a casual game.

Then later if you want to play at all you have to keep up with your group/posse - which means 24/7

Maybe it will slow down after the 50th raid of the instance with the best loot
About the time a new expansion turns up

Maybe if he doesn't care that much about actually doing things in the end game or if he goes through a crafting streak he can still play at high levels and spend time with you.

Maybe there is a group of casual high level players he might fall in with - (but these are not usually very respected I think and can be hard to find).

These are just the trends I have seen.
