Ex-girlfriend admitted she has abandonment issues?

So my ex-girlfriend and I embarked on a distance relationship, relying on our previous two grateful years of love for one-another. Of course as time took its course she began to distance herself from me, and eventually wanted space. We of course broke up. So neither of the two of us have really put any work into seeing other people and we have been apart for 2 months, and she just recently tried contacting me just before she is in town and she admitted she has abandonment issues. I really love this girl and I know in order for anything to ever work SHE needs to get over those feelings. I'm just wondering if there is anything I can tell her or should tell her. I have been giving her lots of space because we often do things like were still dating then she goes off and ignores me for a while. So basically does anyone have any experience on this issue, and is there anything I can do?
