Tell him I love him

I deadass really like this guy for a long time now and I’ve known him since sophomore year of high school and now we’re in college. He went away for college and I stayed to go to community but idk how to tell him how i feel. He’s super sweet and helpful and just amazing. We FaceTime talk and text almost everyday until like 4 am. Maybe he’s just being nice to me so I’m unsure on what to say to him. It’s already a long distance between us and it’s going to be even bigger once I move to another state. I dead ass really like him. His personality his humor his smile. Like everytime I talk to him I get butterflies. I’m deadass 18 but feel like a child when I’m talking to him.

Update: I haven’t told him But now he won’t message me back :(
