T, let's tweak your perspective just a wee bit because you're on track, so consider this: Let's say that right now, she's not interested in coming back, but she is interested in doing things with you. That's good enough for now. It means she enjoys your company and is agreeable to stepping up that time with you, and that suggests she still has positive feelings for you.
As you step up these times together, and make them happy and positive, and accumulate them, her feelings for you can follow and grow. She can change her mind.
I just wonder if when she starts to work whether the new people she meets will cause this to fizzle.
You're worrying about scenarios. Even in healthy, loving relationships, people meet other people and there's risk. Don't find imagined things about the future to worry about today. If her feelings for you grow, and you continue to feed her "love bank", other people are likely not to have that pull on her.
