So there's this girl at school that I've been head-over-heels for a really long time. I've attempted to ask her to hang out and she has said she wants to, but every time I ask her to she's always busy. I've verified that she has actually been busy when I've asked her, but I feel like she's just not into me. The hardest part about all of this is that I've tried moving on, and finding someone new, but I can't. Every time I see her, the feelings that I've hid deep inside my heart burst out uncontrollably and I have to start all over again. Does anyone have any tips on how I can get the girl and or move on?

Hm... Idk if this will help but I kinda was in this boat once. An ex of mine I still had feelings for but I hated how she treated me... to move on I just didn't look at her, be around her, talk about her, just kinda blocked her out of my life.
If you're really set on moving on maybe try that? If not maybe try to just talk to her again? Make sure for a fact about her feelings towards you. Her answer might help you move on too.

I don't think she's into you. Because for me as a girl, even though I'm busy. I will totally find a way when a guy I like ask me to hangout with him. Girls are easy to read when they like someone.

Not always easy to read... it depends on the girl.
