I really liked this guy for a long time and its gotten to the point where I don't even think I like him. I think I love him. But he doesn't like me back. It took all my will-power not to cry over it but I can't stop myself. I can't get over him, I can't find someone else to like, and I can't not think about him. Its like he's all that matters to me.
What should I do?

I've found this quote so helpful and I'm getting over him good luck xx


"If I never met you, I wouldn't like you. If I didn't like you, I wouldn't love you. If I didn't love you, I wouldn't miss you. But I did, I do, and I will.”
