I don’t know what to do

Recently I started liking this guy. I think about him all day every day, I want to know about is hobbies and I want to be around him all the time. Maybe it’s just too early for him to catch on or something but I just can’t tell if he likes me back. I’ve caught him staring at me and he laughs at my jokes but like I’m just so confused. He’s so smart and honestly the prettiest boy I’ve ever met. It kind of hurts because all my attention is on him and I’m not sure if he even notices me. The school year is almost done and I won’t be able to see him because of the summer. Probably the worst part is this beautiful bitch has like zero social media. We hardly talk but just being around him feels like a giant weight is lifted off of me and I can’t help but smile at him. I’m literally hopeless. I don’t know what to do!!! What if after summer we don’t talk at all and he forgets about me? What if he doesn’t like me? I can’t just move on I’m basically obsessed with him. Should I ask him out or is that cheesy for a girl to do it? I just don’t think he will get the hint if I don’t. HELP
