Am i in the wrong?

Hey spacehey people!!>⩊< I experienced the worst breakup ever, and I was the one breaking up. See, there's this guy on whom I had a crush like 2 years ago, and on Christmas, he randomly texted me. (ó﹏ò｡) He was really sweet, but not the same as I remembered. I don't mind it, but at the age of 15, he's hitting the yart every day. And again I don't mind that, but it's all he ever talks about...(ᵕ•_•) But besides all of that, I gave him a chance. He was really clingy, and I don't really care, but he was holding me back. Like LITERALLY. I couldn't hang out with my friends without him asking for my location or texting me EVERY 30 MINUTES. (¬_¬") I'm not an overprotective person, and I don't want to be with one. So basically, we hung out a few times, and after those hangouts, I made up my mind. I'm going to break up with him. And I did, but after a really fun hangout. I mean, I just realised I see him more as a friend, NOT a boyfriend.( •̯́ ₃ •̯̀) So I texted him, telling him what I feel. And he was so heartbroken. I mean, he even started guilt-tripping me into saying he would quit for me, and that he always loved me. After all of his paragraphs, I gave him the idea of us just being friends, and he agreed!!(˶ˆᗜˆ˵) I mean, it was really fun hanging out with him and gossiping, but I see him only as a friend. We were like chill until he started texting me paragraphs about how he would always love me, and he just thought that we were real. I felt really uncomfortable after explaining to him that I had no romantic feelings, so I explained it again, but he didn't stop.(¬`‸´¬) I got really sick of explaining the fact that I DON'T LIKE HIM to him, so I just blocked him. So was I too mean?
