I think Juliet should choose Edward because he seems really nice. Montgomery could have always came back for her but didn't, but Edward stays with her.
I think she should choose Montgomery because he has been with her since the beginning.
I believe that Juliet should choose Montgomery. I feel as if that even though Montgomery has done horrible things, Juliet still knows most of his past and the mistakes he has made. Edward ,however, is a wild card. Juliet barely even knows the guy, and neither do we. For all we know, he could make Montgomery seem innocent.
