I am sorry you’re going through this. The older we get, the more difficult it can be to get invested in someone emotionally.

What you had was a perfect storm of Distance and her Immaturity. You almost can’t get mad at her ~ she is still immature, half baked, crazy. I’m sure she will be a lovely person ~ in ten or fifteen years. Unless she is very young, she is a late bloomer. What mature adult woman lets herself get caught up in a long distance relationship unless it was serious?

Instead of saying, “It’s all over!” try saying, “Maybe one day, who knows?” This will help you cast her loose, mentally.

Consider her a blueprint for what you DON’T want in a relationship. And then, when ready, find a mature, local woman.
