Stalking

How do I stop stalking this guy I’ve been hooking up with? I know his YouTube channel his Instagram and TikTok. I’ve known him since I was 19 I lost my v card from him. We been on and off only hooking up. He would ghost me and then we hook up. We blocked each other and reach out to each other on text now apps. I recently got out a relationship for 5 months. I recently hooked up with him twice. I can’t stop thinking about him.
