Chastity in vanilla life discussion

I’m completely baffled. Tonight I told my girlfriend that I need some action, but she laughed and said no way. So I figured I’d probably just jerk off tonight once she’s asleep or tomorrow morning in the shower. Then she was like, “go put on your cage.” It had been about a month since she brought up the cage at all. I asked, “Really? Are you serious?” She replied, “Yeah, but I don’t think you will.” I told her, “I’ll do it if you want me to and if you’re really meaning it.” She didn’t say a word. So I pressed further, asking, “Do you actually want me to?” Her answer was simply, “No.” Now I’m totally lost and unsure of everything.
