Bro just cut contact and move on. see a different provider or a sugar baby if you have to distract yourself. but this shouldnt be happening.
Whats your sex life and relationship life outside of this hobby? I think I already know the answer.
Some serious self improvement is definitely in order. get in the gym, eat healthy, make money, develop your social skills.
cause the harsh truth is whenever I see these posts: not all, but alot of providers will offer to hangout with their clients for free , will ask their clients on dates etc. If they like them. its happened to me a few times. its happened to other guys I know who participate in this hobby. Guarantee they are having sex for free with guys on the side for free aswell, wouldnt be surprised if those guys dont even know she is a provider. if she liked you, you wouldnt have to pay.
I bet if she knew you wrote this post, she would feel like you were sad, creepy or pathetic . or she would be laughing at you with her friends. harsh but thats the reality.
self improve and get laid or atleast go on dates outside of this hobby.
in the future , dont book long sessions, dont repeat only with the same girl. etc.
