You should follow your heart. If you want to be with her so badly that you don't care what the end result is then contact her. Just keep in mind that she seems to be either fickle or too young to really commit. Her new life may offer her freedom to really explore life. That can lead to this very confused way of dealing with life and not knowing what she wants. Her age alone of course can also be the source of her confusion. You have to decide if taking a chance on being rejected is worth it. If you really love her then it may be worth it. That decision is yours. I can't make it for you. You know how much you want to take this chance.
Weigh out how bad you want to take a chance on this relationship. You have to want the relationship more than your concern about being hurt. I don't know her motives but I fear that she may be just too young. Don't allow yourself to be a pawn for when she gets lonely.
