Seriously, someone should just sticky a one-itis thread or something cause the amount of these threads have been ridiculous.
However, I shall answer your question anyway.
First off, don't delete her. I have had some issues with a girl I deleted long ago and lets just say it didn't end well. Meeting her on the streets didn't help either. Awkward.
With that being said, the reason why people have one-itis is because they lack options. That one special girl comes along and shows interest and you suddenly label her as special. Guess what? She's not special. The cure is to go out and meet more people. Once that special star, she will no longer be a problem with the many stars that will be in your life. If she comes crawling back, well, now you got more options
