That's a very hard question, i mean Raoul loved her ever since they were little. And Erik kidnapped her and loved her also. I don't know what i would've done. Erik wanted love and needed love, Raoul just sort of seemed like a puppy dog to Christine. Always jumping at her commands. I think Christine did the right thing by showing Erik love, but leaving him. In the end it worked out right. All i know is that i never want to be in Christine's shoes.
