So every night he comes over to look at the stars together (he's my neighbor) and for some reason he didn't come over last night. I asked him if he was coming and he never answered me. He finally answered 2 hours later with a blank screen saying idk. He usually always snapchats me a funny picture at 2 in the morning to wake up to and he never did. He's not answering any of my texts. I've walked passed his house and his window was closed (usually it's open). I'm really confused because idk what I did or what's going on.
