I’m very confused please help me

I told my crush that I liked him and I feel so dumb for doing it because in top of telling him I apologized when I told him and he said “alright”. So afterwards I decided to apologize more and said

“I’m sorry, I know you don’t like me. And I am sorry, because I don’t mean to like you. And i wanted to say I’m sorry. I’m sorry for telling you and im sorry for apologizing a lot and I’m sorry for being annoying and having a crush on you even though I know you don’t like me. :”

He didn’t respond after that but a couple days later my cousin tried to FaceTime him not knowing who it was... so then I apologized for that. And he said “alright”. I know he doesn’t like me, but I think he should say more then that right? Or did I come off to strong and he had a right to just respond in one word with no punctuation or capitalization? Did I scare him away more? Did I do something wrong? Please tell me, because I’m just here on my bed so confused.
