She may be insinuating that she wants to remain friends.
In essence, she is telling you that she has already turned down your offer and thereby she has demonstrated that she doesn’t want to get into a relationship with you.
However, in telling her good luck with her future and not contacting her after she declined your attempts to make her your girlfriend, you may have put her in a panic.
She may fear that she is losing you as a friend and she doesn’t want that.
Her entire motivation for this meeting may simply be to keep you as a friend.
