She (blank) because he (blank) SPOILERS
So she left him because he said he didn't want to have children? So she runs off? Not even telling him that she is pregnant, she didn't even give him a chance to be the dick in the relationship. She made herself one. How cowardly was that. At least let him make the choice. It was HIS child too. It just came off as selfish to me. Making her sister swear to NEVER tell him about the child... I mean, if she cared about him at all, knowing he was an orphan, never knew his parents... why steal his chance at a family. If she REALLY loved him you'd think she would not have done it.
Maybe there was more to the book, but the movie left much to be desired with her character (for me) I didn't like her. His decision to pursue her also didn't endear him to me either. But I liked him better. I preferred the war part, which is sad because people were dying horrible deaths.
