We split, stayed friends, then when we all moved on to college i had this massive argument with her, like everyday for a week and basically never spoken to her since, she is one of the only people i actually hate. So yeah, don;t do it if you still want the friendship.
You may think it'll last whatever happens, but trust me, it shall not.
