What do you think about this?

So, I asked a girl out to homecoming dance at out school at the beginning of the year. She said no because she didnt think she was going, and another guy beat me to it. I started liking her again lately, I've been texting her a little. Anyway, I'm thinking about asking "Had I asked you out first and you knew you were going to homecoming, would you have said yes?" And if she says yes, I'd ask "would you say yes now?" or something like that. I'm not sire how that is, but it's my best thought. Tell me what you think please. Thanks!
