help?

okay so I've liked this one guy for a while. i got his number from a friend and texted him, just a simple hey no name or nothing. i ended up getting blocked because he didn't know who I was. for awhile i was mad and I was talking to my friend about " oh i hate him" all that bs i was telling myself to get over him 🙄 but it's so hard to not like him? he's in my classes and his best friend is one of my good friends. i just cant escape dude
