Is this love or just a silly teen crush?

My other crushes lasted a few months. This one is over a year and still going. I’ve cried about him like 10 times already. I wrote songs about him. I fantasize about marrying him and living together. I never fantasized about marrying anyone before. I literally dream about him in my sleep. When I’m around him, it’s like a rush of adrenaline and I feel like running forever. Is this what love feels like?
