I can feel the same way at times since a lot of the people I've gotten to know over the years in WoW, have grown tired of the game or they play MANY games and don't feel motivated to keep playing WoW. I on the other hand just gets more and more tangled in this game, especially now with MoP having been so much fun and I rarely have other games catch my eye...if they do, then I only get like...30 hours total out of them? My MAIN toon in this game I have played for 258 days in total. That's not counting my 11 level 90 alts as well .
So yeah...misery loves company, that's what I say when the people gone emo over WoW are trying to drag me down with them. As for you and your boyfriend...there's nothing for him to find weird, you enjoy WoW enough to not need other games...how's that weird? o.O.
Also, on the populated servers you NEVER feel in minority. I moved from a dead server to one of the most crowded, and I love it. It was like rediscovering the social part of the game all over!
