So there is a girl that is in same class with me for like 2 years and we were on a birthday party, get couple of drinks, danced but not kissed. After a week or so i ask her out and I took my friend and one her friend. I got c*ckblocked by that f*cker twice and since then I didn't really talked with her too much, but I still liked her. Now it's our graduation and I asked her to be my prom and without thinking she said yes (before me she refused one guy). Now we are cool but I am not sure if she likes me, cause i really do. I can see her sometimes staring at me but when i talk to her i don't get that flirting, she's kinda cold like nothing happens.
Now I really dont know what to do... If I tell her now that I like her and she refuses that would ruin our prom, cause the party is like for a month.
Please give some advises :/
