No and yes.....he wasnt her first choice to begin with she had to learn to love him he could do a lot better.. besides he had to of been with someone else, before rose found him. am i right!!?? theres an untold story
Personally I see there relationship like one of those in high school where the star football player dates the head cheerleader because that how people thnk it should be. But to answer your question I dont think Rosalie deserves Emmett. She always complains how she didnt want to be a vampire and that if she had the chosse she would give Emmett up in a second to be a human and have children. I feel soo bad for Emmett when she does that.
