I'm 14 and I really like this girl in my class but I don't know how to ask her out.?

Well you can't ask her out without knowing if she is into you. So give her signs that you like her like holding eye contact and flirting with her as in complimenting her and see how she reacts. You can tell she likes you if she smiles and or turns red from shyness depending who she is then ask her as a casual friendly thing if she wants to hang out with you outside of class and if she says yeah then your onto something if she says no its no big deal you asked her as a friend to hang out. Then keep it building from there. Hang out with her a couple of times after that and then if everythung goes by smooth ask her out. Ask her out when you guys hang out or maybe during lunch. Just say, " Hey. Your the type of girl thats "Wifey" material. What would u say if i asked u to be my gf?"dont directly ask her just ask her what wud u say....
