That is sad! My boyfriend froze his account a couple months ago. He's the only reason why I was playing to begin with! And we always quested and pvp'ed together. At first I felt a little lost without my permanent back-up, in battlegrounds we always topped the damage charts because we looked out for each other and that's not easy to find in pug situations. He guided me through everything, from learning quests to which guild I was in.
While he was playing, I made a lot of friends that were his friends, too... and I've recieved a lot of support from them since he's been gone. Of course, they are always asking when he's coming back, too
. Also, I have since made new in-game friends that I can rely on and have alot of fun with them... but I still haven't stepped into a battleground. It's good that he's your real life friend, too, so you know he'll always be around. I do feel your pain, but don't worry! You'll still find ways to enjoy the game!
