How do you know if a guy likes you?

I (17F) been talking to this guy T(18m) for more than a month now I met him at a show and saw him again at other ones too the 3rd time I saw him he asked for me and my friends number so we could go to this abandoned place together and he wouldn’t stop talking to me that same night until 3 am ever since then during winter break he wouldn’t stop texting me and calling me almost all night practically every night he also bought Rust and Cruelty squad for me so we could play together

He says he like it when I yap and the last time I told him I was going to a show he was going to he said he was excited to see me and it feels like it’s been years he also loves talking about history and music with me and half of the songs are love songs we also call a lot still even after winter break to watch breaking bad I think he talks to his friends about me too because his best friend knew my name before I knew who he is T texts me about his day and he always wants to know how mine is he asks questions and is genuinely curious in what I have to say

Me and him are going to this arcade on Saturday and I want to ask him out but I’m really scared he’s just really nice and doesn’t actually like me in that way
