Honestly, if she's been struggling with personal problems, and you still care for her, maybe you should try to talk to her again. If you already ended on good terms, it would still probably be easy for you to go up to her and just talk. Mostly, many people just need someone that will listen to them, so maybe you should go up to her and help, if you care for her and want to see her be happy. Although I don't exactly know what your situation is, that's what I would do.
