why is the girl i like ignoring me?

Sorry, I can't really tell if she likes you from that much info, but she obviously likes you as a friend (at least!) if she wants to be out alone with you.
Maybe she thinks she's been too pushy or doesn't want to seem desperate. When I like a guy, I'll ask him to hang out, and if he says no for whatever reason, I have to admit, I get paranoid and think he's not into me :/ just explain your situation to her and let her know that you're into her
Good luck! Hope it goes well for you
