My dad once told me about a quote in one of the novels that said, basically, that sometimes someone loves you (or falls in love with you) simply because the other person loves (or is in love with) them. Does this ring a bell to anyone? (In my recollection, the quote did NOT come from one of the most famous novels, such as Pride and Prejudice or Sense and Sensibility. I'm thinking more like Mansfield Park, Northanger Abbey, or Persuasion.
