I really don't know (and I'm not sure I would want to know). Half of me would like to think she thinks of me often, and the other half is positive she doesn't care about me and never thinks about me. Both of those are probably wrong; realistically, she probably thinks about me just occasionally, and that is probably prompted by something that reminds her of me somehow. I find it doubtful that she just ruminates about me for no reason.
