Glad to hear that the situation wasn't quite as dire as it first sounded. She sounds pretty reasonable about the situation and your response was as well.
All I can suggest is that you revisit your feelings for this woman every so often. Your both still really young and going through a lot of changes in your wants and needs. Don't be shocked (and I'm not saying its going to happen) if you do happen to drift apart. The old addage of 'if you love it, let it go. If it loves you it will return' is quite true.
Best of luck.
