I was devastated she didn't show up I've been trying to get back in shape for her and I made her favorite foods to eat. :

How long has she been going out with this guy? Get someone who knows some of her friends to find out if the guy really likes/loves her. If he doesn`t like/love her or he is a complete jerk, then maybe you can do something original and sweet to win her back. Tell her how sorry you are, how much you still love her, etc. And if you really do, she`ll be able to see that.
