Whats with the questioning?

My ex girlfriend keeps asking me random questions like brownie or cake, Boxers or briefs, Blowup doll or lifesized barby, hustler or playboy, and much more. and she sometimes says answer or I'm not talking to you until you do. then i don't answer and i get no texts for days until i text. I'm not really sure if she still likes me or if shes just playing with me. Cuz I haven't actually talked to her face to face in a while. Keep in mind shes a highschool student
