Why do girls stalk their last crush on social network sites (e.g. Facebook, Yahoo answers etc...)?

Anonymous
So a couple months ago this girl and I both had a crush on each other, but we never got a chance to go out because we were both moving to different states. Anyway we both have accounts on a Q&A site (not this one) and we started talking for a while and she mentioned she had a boyfriend etc... I asked a couple of questions, she asked a couple and we both answered each others questions. So the next day I receive an email from her and she said she has been stalking my profile for a while... Which I don't get.

Why is she stalking my profile if she has a bf?

Does she still have feelings for me or something?
