I first read the title as "Girlfriend
Dates WOW Characters, Dude Destroys Computer," and didn't find anything weird with that.
Dating game characters is nothing unheard of
I've never been interested in WoW. I've played a friend's character for about half an hour and decided I didn't really care for it.
That aside, deleting someone's account is a dick move. WoW is a hobby, one you put much time, effort and
money into, and your character is what you have to show for it. Sure, the only ones that would value something like that are other WoW players, but it's something that took a lot of work (even if it didn't feel like work), and deleting it is like breaking someone's model ship that took hundreds of hours to build.
Of course, partners scorned have been known to break stuff so perhaps that's exactly what she was doing. And it's still a dick thing to do. "He's not paying me enough attention, I'ma break sum 'his stuff, mkay."
Dick.
