If you jump because she added you to her facebook and made a comment on a picture, then you're too easy. It's possible that's she's testing to see if there is anything there, but don't jump. She's an ex-girlfriend for a reason, and she shouldn't be let back in your life so easily.
Most people on her say keep your exes as exes, but that's something you'll have to decide on your own. Just don't be so easily moved by her. Let her be amazed by your self-control and independence.
