I don't want to be so blunt as in saying "keep your options open." but I would maybe try to show her how much you care. On the other hand, I think she may need some space. It's not the best sign that she is even thinking about this. You and her have been together for to long for her to be reconsidering the relationship. I hope it works out for you and if you want keep us updated. IA>Relationships lol
