How to block him and am I avoidant?

How can I cut off a friend quietly and unnoticeble by him and our mutual friends?

I have this guy friend and he's great. Lets call him Hernando. Hes attractive, humorous, and we overall vibe together (at least for me). When I first meet him (at a school zoom call) I was instantly captivated by his looks, I liked him sa face card niya, a ramdom batchmate who I thought I would never encounter ever again. I thought at that time he was just all face no brain.

In our school the following grade level (Last A.Y. for SHS), our sections would be randomize. And guess who do I get to be classmates with, its Hernando. Pero at that time, I didnt think about it bcs I had a boyfriend in the first half of our school year. Eventually, we broke up and I used hernando to quickly get over my ex-bf. Now at this time, Hernando and I didnt know each other at all, he was just eye candy to me. And I was using him kasi he was the only guy in our room na pogi and was basically a random bystander. After a while, His "girl best friend" and I started to get real close as in, I basically befriended all of her friends bcs we clicked that much and that included hernando.

Through this girl best friend, I got a chance to get to know Hernando at a deeper level. Through this, I found out that he was just more than a face. He has an amazing talent for singing and playing the guitar, his interest would aligned with mine, and he is a very smart man. It turns out he is a 10 on all categories (academically, charisma, looks, musically, gaming, & etc.). One of our hobbies that we both liked is ML, we would play together consistently through the school year and I was basically attached to him as a friend, but to my side, I wished I was attached to him MORE than a friend. Through him, I also got to know his friends and we would play together.

The problem is, we are all in college and I wanna move past him. I want to forget all about him. The thing is my feelings for him is not explicitly known yet (and I plan on never revealing it), though we had pangangasar na "crush ko raw siya" pero Ive always denied it. Kasi sa eyes niya, we were just friends and I didnt want to ruin it by confessing my likeness to him.

This is only gets worse for me and my feeling for him. Even though summer break na and we dont see and talk to each other. I would dream about him almost every other day for a short period of time and one of those dreams was soooo gooood.

Sa dream na yon, It was started by a friend pala (idk paano nagyari yon. Maybe dahil sa pagkwento ko araw araw, nanaginip si girl about samin and kinwento sakin tapos ako na nagtuloy 😭) so nagsimula ito si hernando pumunta sa school namin while it was raining heavily, he ran and came to me as fast as he can to express HIS feelings for me (halatang panaginip kasi paano siya mag coconfess ako nga may gusto?, delusionada talaga ako) and I was like declining kasi pakipot pa ako, pero he was still insisting. He said he made a mistake and he liked me pero he was confused at that time. Ako naman after reading that, kilig naman ako, so I said yes.

So sa panaginip ko naman, naging kami na, we were so happy together para bang married couple na kami, he would go to my house and chill, we would do the boombayah (still a dream) and his sword is so big (!) And i was so happy kasi yes me and my crush are doing boombayah sa dream ko. Everything felt so real pero at the end of the night, gigising ako sa realidad. Minsan gusto kk nalang gayahin si Wanda, na para bang gagawa ako sariling reality na pwede maging kami.

So halata naman na sobrang delusionada ako diba, kaya gusto ko na i-stop. Para sakin for this to stop, I need to stop thinking about him, kailangan ko na hindi siya makita ever again, kaya gusto ko siya i-block on all socmeds and never see or talk to him ever again. Kaso yung friends namin malalaman if I did that. Our lives we basically so interconnected na malalaman agad ng ibang friends namin if I blocked him.

Actually nung magkasama pa kami nung SHS, Ive tried to cut him off, pero he would always reach out with questions "why did you deact?", "why did you unfriend me?", at "bakit di niyo ko pinapansin?". I wanted to do what I always do, BLOCK siya para maka get over nako, pero I feel like he would make a fuss about it and the whole world would know about it, thus confirming my feelings for him.

How do I cut him and keep our mutuals together without them raising suspicions that I stopped being friends with him? How do I get out of this situation? Plss help mee
