Idk if i have a crush on this girl

Lately ive been getting close to this one girl, lets call her Milk. And shes so sweet and like nice to be around. Lately ive been thinking of her more. Idk how something just snapped inside me when we went out a group for an event. And ik theres this one guy that likes her. And i was staring at them interact from afar. I felt like tearing up, i thought at first it was because i know nobody would find me attractive, but acc i think it was because i was JEALOUS OF THE GUY
cause i liked her and i didnt want some guy to take her. But idk if thats considered a crush. And lately i just wanna hold her hand.
