online disciplinarian sad story

I had a girl on here who wanted me to be her online disciplinarian. I agreed. we had an on and off relationship over the years. At first i thought she wanted this to be nonsexual which was fine but she started sending me nudes which i was happy about. but when i wanted more she tried to shame me and said sex was all i cared about. so we agreed to just be friends. then she sends me a message telling me she dont want to be friends either and to never contact her agian. i got angry and said fine and blocked her because i wanted to honor her request and if i didnt block her i would be tempted to contact her again.
I feel bad that she thought sex was all i cared about and i did value her friendship. Im also appreciative of the fact that she told me not to contact her instead of ghosting me.
I just felt like ranting.
