It sounds like he broke up with her and she's still a little hopeful that they might get back together, though I could be wrong. It depends on how many times she's on Facebook or MySpace. My friend's ex still has 'I love insert name of ex-ex-girlfriend here' on it because he's hardly ever on. Still try to cheer her up without being annoying, although she may not look sad, she maybe keeping all those feelings pent up inside. If you were to try it early, she may have thought you were belittling her feelings.
