This boy I have loved for so long..my feelings are here to stay..forever?

Well, you obviously are obsessed with him, I would say that he is just too shy to talk to you too, but when you said that he blocked you and you think it was because he doesn't want you to talk to him that's kind of a red flag in my opinion.. I hope things work out for you but he might not like you, it happens you will find another, but keep in mind that you are only in 8th grade. I know how you feel, I liked my boyfriend for a long time before we started dating, but that's more of an exception in my opinion
