So she isn't ready for a relationship, big deal. She still hangs around and does seem like she is trying to decide. I let anger get the best of me. Don't do the same.
As for lunch, who knows what it means.
Also, I would like to address the idea of goals. It is my opinion that you set goals for yourself. Be the best you can be. Don't set goals for her. All it will do is frustrate you.
