She gave you a nice big hug? You find that as a positive thing? That's what friends do, not lovers.

Did you try to kiss her? It isn't clear. If you didn't try to kiss her on the date you fucked up and is why she is over it. Always kiss on the first date. Show your intentions. If you didn't go for the kiss she either thinks you are a pussy or you don't like her. She isn't going to make the first move, it is your job as a man to escalate. And you should always be escalating.

If you would have went for the kiss you would have known where you stand. If she gives you the check she isn't into you, if she kisses back she is into you. Now you are in this weird friend zone purgatory
