i think my crush likes me

so i'm in high school and i've liked this guy for about 6 months and i don't know if he likes me back. he's pretty shy so it's hard to tell. but we always are really sarcastic and can make jokes back and fourth and he always asks me personal questions like what i believe in and what i want my future to be like. and in one of my classes his friend always says things at him when we're talking but i never know what he says, all i know is that his friend will say something and he'll tell him to shut up and he'll blush a little. but he never has said to me that he likes me or anything, and he might still have a crush on another girl. idk do you think he likes me?
