If a girl says she doesn’t hate me, it’s too late to love you! Is she kidding? I consider her a good friend.

It doesn’t matter whether you are joking or not, what matters is what you think; if you are really not interested in her, then treat it as a joke and continue joking with her. If you want to get along with her, just do it. Say some ambiguous words and ask her why she loves you before it's too late. The key is your own thoughts!
