Elena Gilbert... Who will she chose?

So we all know Elena is torn between the 2 Salvatore brothers, Stefan and Damon, right? I mean, who wouldn't be?

But the question is.. Who will she choose?

Stefan, the sweet and protective brother who's willing to do anything for Elena?
Or Damon, the dangerous, impulsive, and charming brother who secretly loves Elena and would do anything- even give her up to Stefan?
There is always the question of what will happen in Season 3 when Elena realizes her goodbye kiss, will end up being a hello kiss. And what will Elena do when she realizes that Stefan has left her and has turned to human blood and joined Klaus?
Both love Elena of course, but who deserves her more? Or... who is her true soul mate?
