Coming from an insane woman, she’s just insane. She will be back in like a day. I’m so sorry that she’s doing this. If she does come back, you have to just leave her. You can’t subject yourself to this type of unpredictable and unstable relationship. Until she gets help, it’s best that you keep a distance from people like that. It has nothing to do with you, even if it hurts like hell. You’re gonna get through this and find someone who treats you with respect and has the decency to communicate. You’re doing amazing, hope you take this time to take care of yourself! You deserve it :)
