advice please urgent

So 3 weeks ago, it was raining outside my uni heavily and my friend was on the bench with an umbrella when we met this other guy. We all started talking as we were all new and so I made a groupchat with us all. He dmd me separately and we started talking about music. Soon we would meet up during uni and eat lunch together and walk and talk as well. Then we started to hug, which I did first since im a very affectionate person. He told me he wasn’t used to that but I asked him if it was fine and he said yes. Then he would ask to meet near the station and we would talk alot and he would tell me how he liked to talk to me so much. Then one day I was late and he was a bit annoyed and so I wrote him a note on paper saying sorry. He seemed to enjoy my notes. recently (last 2 times) he decided to stay with my train until the end and told me how he loved to talk to me. On last Friday especially we hug on the train. I always said to me you’re a really good friend and stuff. I meant this all platonically. Today he bought me a coffee and everything was going fine. This guy who flirts with me did so in front of me and I got told how he is a bit jealous of other guys talking to me. He asked me to meet him in the parl after the lecture and asked me ‘what does it all mean’. I told him I had no feelings for him, it was platonic. After that he acted really strange, saying ‘the sun has set’ and that we have overstepped boundaries and it’s a bit embarrassing for him. I told him that I dont feel any difference but I feel sort of disgusted for him thinking like that. i left and just before that he said that he thinks that things can’t go back to normal and how the notes I gave him were ‘weird’ and how when I told him he was my fav person in the world that was a lie. He said he doesn’t know who I am and it’s better for us to just be mutuals. I was hurt bc I loved spending time with him. I unfollowed him on socials but couldn’t stop thinking about him. I texted him to meet me tmrw as I need to giv e him something but by this I mean that I want to really have a convo with him. Btw when I said at first that I didn’t understand what he meant he said that hes not into me in that way after I said that. Anyways I texted him and now he says hes okay to meet and it’s more adult to do it that way, and now talking about how we went out with his friends and hes drunk. a bit rude on text, saying he gets it but hes not in the headspace rn but he will see me tmrwLike can someone tell me maybe what he felt?? Bc I feel so awful right now
