I think it is merely an infatuation

Idk if this is the place to ask but here we gooo. Ok so theres this guy who I've been chatting for 2-3 months, he's a really popular guy, he's smart, he's got looks and lots of peeps got a crush on him. K so we are not close irl and we dont have the same friends and like it is a situation where no one would even expect that we will talk w each other but yea we go to the same school. and just this school year, he transferred to a different school and this is the time we started talking to each other online. So like when we first talked, he was kinda flirting w me so I just went ahead and do the same lolol and like I did not realize that we've been chatting for an hour thats it. Then after a month of chatting, we went to the "talking stage/mutual understanding" idk the term but yea. At first, I seriously was so fond of him and was always waiting for him to chat me. We shared a lot of infos about ourselves from hobbies, interest, problems in life, and even family problems which made me fall for him more. But the problem is that it is my first time to experience this. we talked a lot but overtime each conversation we get keeps getting shorter and shorter and pretty much because of me. One factor is that we have different interest and hobbies, Im glue'd to my computer 24/7 playing games, watching animes, and reading shits and he's more into having a conversation than any of what I love doing. I had a past of being lithromantic as well and I think I still am(mind u, i had a crush for 3 and half years before this). Another thing is that I've realized that I am not ready to enter in a relationship because I still havent gotten over my gaming addiction(im a smart/top student even though im a game addict ok dont judge me). So like im totally a newbie in a deep relationship. So here, I want to end it but I dont know how. He's been really affectionate and I feel so bad. He always send me reels which talks about how ppl easily gets tired of him which kills me. Idk if im tired of him or is it just due to the fact that we dont have any similarities with what we do. So please send advice on how I should end it..., relationship aint for me... I think after this, ill be single all throughout my student life (feel free to criticize me, I admit that i am so stupid)
