Boy drama

So there’s this boy, we can call him J, and me and him where talking for a while but I lost feelings rather quickly, idk why tho, but I ended up liking his best friend ( yea ik boy ideal and mean) and we can call him E, I swear I’m in love with E, and me and him kiss and flirt all the time but idk if he’s wanting to have an actual relationship with me, but J is willing to give me the world rn, but I am just so hooked on e, and idk what to do...
