I thought i had a date for homecoming but... want to go with my crush/ fromer friend??? idk if we were. help!!?

okay. i dont know if he and my friend? brian were actually friends but heres the thing. last year i would talk to him in spanish and i saw him looking at me across the room one time. at a choir rehersal he got my friend to point him out across the risers so he could say hi to me and wave. she told me he was a jerk and i believed her and tried to stop talking to him. it sort of worked only because it was the end of the year and i didnt see him over the summer. i saw him at a school orientation and said hi as i walked past him and he said hi. but later, when school started, he didnt talk to me AT ALL. i realized i really like d him again after i said hi to him. but since we dont really talk, i tried to get over him. me and my friend sarah asked this one guy in my language arts cl if he would go to me and he said yes. the problem is that we NEVER talked. then i asked my friend to ask him if we were still going to homecoming. he said no. i mean really, why didnt he atleast tell me?! dammit now its less than a week away and i really want to go with brian to homecoming but we never talk. its so akward trying to talk to him. should i try one more time to talk to him and be like hey whats going on? i havent talked to you in forever. or was he just talking to me in spanish just because he could? i thought he liked me:[ i wish i could know y my friend thinks he is a jerk but she moved and we dont talk that much. what do you think i should do. sorry this is a little long but i want a really good answer.
