Getting over a girl

im 16 and in high school and i was going out with a girl for about 9 months and i really loved her with all of my heart and she told me she loved me all of the time. when summer came she told me all of a sudden that she wanted space, which eventually led to her telling me she no longer has feelings for me. Not because of anything i did
but because she doesn't know why. and of course that answer makes me crazy every single day. I thought about why she just wouldn't have feelings anymore for about 2 months non stop, and i consider myself a smart guy and i still couldn't come up with anything. So please, if you could just give me some sort of way to understand why she would do that. and if you cant do that, please just tell me how to get over her, because i wake up everyday and hate going to school because i see her and it makes me feel aweful.

ANNNNNNYthinggg you can tell me
would be a great help
thank you very much

Love comes an goes. This is the nature of love. After a few months you might not be in love anymore. This is terrible for the one who is still in love. You need to mourn and then hopefully find a new girlfrind, much better than the old one, so you can feel happy, that you got rid of the old one.

Read about mourning.
