Since elana is sired to damon, and it happened because she had strong feelings for damon beforehand, do あなた think that damon will actually be able to break up with elana?

Damon wants Elena to be happy,and never wanted her to be sired to him so the answer is yes he will break up with her, also he loves Stefan and would never want to end their relationship.

yes, the sire bond should be broken. so damon and everyone else can know that elena has real feelings for damon.

Yes, he is going to break up with Elena because, when the thing goes to Elena he always do the right thing for her.

I sincerely hope not ....just sayin :P
