Months have passed and I still haven't gotten over my ex-friend

It's been 11 months and 20 days since it all ended, and I still can't stop thinking about him. I met him on Discord at the end of 2023, and despite being just an online friend, we became inseparable. We talked every day. We joked around, flirted, and talked about weird or personal things. One day (I think it was at the end of 2024), he told me he had a crush at his school. I was happy for him and even gave him advice on how to win her over, and he did. I was happy for him, but after that, everything changed. At first, he gradually stopped talking to me, and honestly, I didn't think much of it since I understood he wanted to spend time with his girlfriend. But then he started ignoring me and talking to me strangely.

When I tried to talk to him, he responded as if he were annoyed with me, usually with an "ok," "...ok?" or "..." (or he simply didn't respond). I felt like everything I said bothered him. I sometimes tend to make sexual jokes with him, so I stopped, but he still seemed annoyed with me. So I asked him if something was bothering him, some joke or something I did. But every time I asked him that, he replied that it was nothing. One day I asked him why he wasn't answering my messages anymore, and he said something like, "Look, I used to talk to you because I was alone and didn't have any friends, but now I go out with people." I honestly don't remember what I replied, but I do know that I was stunned. A few months after that, he was "hacked" because he started uploading a bunch of videos of Arabs and things like that to his account. For a moment, I believed it until another account of his popped up in my recommendations. That's when I understood that he simply didn't want to talk to me anymore, because he didn't even want to contact me again. This is going to sound strange, but after that, I dream about him. At the end of 2025, I dreamt that we were talking again, and he said something like, "I'm sorry for not contacting you, I lost my account and I felt bad talking to you," and then we hugged. Then I woke up. And recently, I had another dream about him, where I was checking his account and reliving memories. I woke up nervous; at that moment, I couldn't help it and I replicated what I did in the dream. When I saw his account, I understood that he doesn't miss me anymore. All the pictures he has are with his new friends, and he looks happy, and I feel happy for him, but I can't help feeling sad for some reason. For about five months now, I've also had this weird thought about whether I really liked him in a different way or not, but I think deep down I know I only feel this platonic love and my mind is distorting everything because of my OCD (if anyone here has that disorder, they know how that crap likes to distort everything about you). And maybe it's because of that same disorder that I can't get over this horrible obsession. Even so, I'd like to know what bothered him about me that made him start bothering me. I know it was just an online friendship, but I still can't get over this.
