sad in love

for two summers straight me and this boy had a fling but he always dropped me to get back with his ex. finally him and his ex no longer talk at all but now he has a different girlfriend still in high school and i hate that he’s on my mind 24/7 i miss him so much i haven’t hungout with him since october and we would usually hangout every single day idk if i will ever get over him and it just sucks
