I hate saying it, but at twenty-four, you've still got PLENTY at time. Also, at twenty-four, many girls I know are still rather insecure (inwardly at least), and fickle. Many still suffer from the "knight in shining armor" syndrome, and are looking for the next best thing to "rescue" them from their current situation.

If she was only in it for the ring, you'll be better off in the long run. Sounds like she wouldn't have been in it for the long haul, anyway.

Sorry to hear about the situation. I'm sure you'll bounce right back. Just make sure to take some time and enjoy your "singledom," get back to what is most important - you - and when the time is right, you'll find someone who appreciates you for who you are - ring or not.
