Chastity and orgasm denial discussion

I have an ex-girlfriend with whom I share a NON-SEXUAL bond, where our connection is primarily one of submissive in chastity and her role as KH. Yesterday she asked me… “what will happen when plenty becomes scarce for me?” I was unsure how to reply. She told me to ponder it. Because eventually the day arrives when she desires more of my frustration, requiring me to be ready and at her disposal or else conclude our partnership now. When we first began dating, she kept me locked up for a few days, then a week… followed by two weeks, with the longest stretch being 20 days. The coming days are crucial; I must decide whether to end things or grant her TOTAL control.
