I want to ask a girl out?

I'm 13 and I really like this girl I've known for about a year now, we're pretty good friends and we have many of the same interests (we both like minecraft and other video game stuff) I'm planning to ask her out on Friday (valentines day) I'm really nervous on what I should do, any suggestions?

Go up to her confidently and ask her to be your girlfriend. Don't say "will you go out with me?" Say "will you be my girlfriend?". I think thats better.

If your school has a valentines day dance that night it would be super sweet to ask her then.

Heart shaped chocolates, Valentine's bear, and maybe a short poem. Lolz and try to be confident, you have a MUCH higher chance if you're confident

Just ask her confidently and directly- "would you be my girlfriend? I like you." Something like that but whatever you do make sure you're confident.
