It's because she loved him so much that she did it. She new what she was doing wasn't right and didn't want to inflicked the same হৃদয় ache she felt on someone else দ্বারা staying with him
Well, that's the thing: she loves him. She knows that he's in প্রণয় with Victoria and she knows that he'll be happier if he's with her. She cared আরো about him than herself, which shows that she truly loves him.
I think she gave Victor up because she knows what it`s suffer for প্রণয় and she knows that it`s not fair taka away Victor`s life because she প্রণয় him. I think it`s ok that she gave Victor up. It`s so good on her personality...
I agree with everyone that it's because she loves Victor and couldn't ভালুক to see him suffer and be miserable without his true প্রণয় victoria,because what's the point in being married to someone who doesn't প্রণয় আপনি back.
Besides there's a saying that if আপনি প্রণয় someone অথবা something, set it free, because one দিন it may come back to আপনি if আপনি let it go. Emily loves victor and victor gave her her happiness back. So i guess that's why she let him go. And why i প্রণয় emily so much. Tim burton is indeed a legend in the film work, right along with Wes Craven.
