"I guess I just worry that if she doesn't find out the things I am doing to better myself she won't even consider getting back together as an option."
She apologized to you. It sounds like it's something that she needs to go through to sort out her own thoughts and feelings. Didn't sound like she blames you at all.
In fact, it sounded like she wanted you to be "okay" with her decision and not judgemental. Regardless of what, it doesn't matter what she thinks.
You continue growing and improving your life. If you can outpace her in this aspect, it may serve as the beacon that draws her back.
