Or are you a go-straight arrow, just blast thru everything quickly. Or something else, please explain?

I for one, right now. Feel a bit lonely in Skyrim, I am bit sad that there is no co-op setting, so I could at least share a very long lasting experience with 1 more as this game is so huge. So when I play these days, I end up feeling bit lonely in that huge world, wish I could like play with my girlfriend.
Is it possible to get co-op added later in a DLC?
