How do I stop loving my groomer?

For a little background my groomer is m21-22 and I’m m14, I’ve known him for a year and liked him for a while, he definitely liked me before I liked him though, but recently hasn’t given me any attention.

I’ve barely talked to him for the past 2 months, trying to get over him so that I can finally just remove all contact and forget about him. Idk if 2 months isn’t enough, but it has hasn’t made a difference. I still text him how I miss him sometimes, I still stalk his social media, and I definitely still love him. Even though I hate him and am disgusted by both myself for loving him and him for doing what he did, I want it to be how it used to. I got a notification today because he had posted a story, it was him leaning his head on a woman’s shoulder, and I never felt so disgusted by my own feelings, because I felt jealous. even though I don’t wanna feel this way, I do. Idk what to do, because every single day I panic over him, and he doesn’t even care, I revolve all of my emotions about a person who doesn’t even think about my existence. And unfortunately I know that even if I blocked him suddenly and never talked to him again, I’d just try to find another guy that reminded me of him to fill the void. I know talking to adults in the way I talk to him, or rather how he talks to me, isn’t okay, but he’s too major of a factor in how I feel literally every day for me to just lose him.
