Do you want to get over him because you don't know if he likes you?
Since school's ending, if you ask him if he likes you and he says no, you'll be able to get some space. And if he's says yes then you can see each other over the summer.
Here are the best songs to listen to:
Speeding Cars by Imogen Heap
I Caught Myself by Paramore
I also have some sad songs I like to listen to, but I don't know if they'll be the best for you.
