BRO HELP ME, sorry for the long test, read if u want, i just need advice

Bro someone who is 18, yes 1-8 told me he liked me- i'm 14 by the way and he knows it-

 'kay, storytime, so i lowkey knew him from seeing him around but we spoke for the first time in my bday, in which most of my friends dumped me, i might do a blog about that too, idk, it honestly depends in how bored i am and in how much i wanna write- but anyways, back to the topic there i spoke to him since my cousin got me and another 2 friends- 2/6 friends who came to my bday, incredible, like i know it's no big deal but if i ever tell the history you WILL understand why i hate them so much, trust me- so i spoke to this guy and he was touching his parts ALL THE TIME so, what did i do? I called him out, duh, so i go like- 'why are you touching ur d*ck so much? U hard or something?' and he put on a lame ass excuse , since that day i have noticed that EVERY SINGLE TIME we crossed paths he would look or try to talk to me- I'M 14 AND HE'S 18 AND UGLY ASF AND A FUCKING PERV- so a few days ago i was hanging out with a friend and we went to the park to drink water and guess what? Him and a friend were there, i paid no mind to them but when i finish drinking? He, who was talking to my friend about her bf, who i might make another storytime about bc what's happening there is a toxic k drama, looks at me and his friend goes like 'hey my friend likes you he won't stop talking about you, he even noticed ur eyeliner, blah blah blah' what did i do? I started to walk away with my friend as fast as i could as they shouted to me that if that was a rejection or not WHAT DO U THINK??? bruh they stayed there all day so we were unable to drink water again. If you read this bible, damn u are patient, if u have any thoughts in what to do PLEASE comment, this is a shitty ass lil town and i'll find him anywhere i go, plus he works in the school i go to so yeah, pretty impossible to escapeÓ⁠╭⁠╮⁠Ò ty for reading, ilyyyy
