Dylan is stupid

ok so first I met him in primary and he told me he loved me so we dated for like only 1 day so I dont really consider him as an ex; lets call him Dylan (not his real name obvy) soo now Im in 8th grade and Dylan was telling to my classmates that we were ex's. Tbh idc bcz its not rlly true but one day he started saying that we were dating, which was fake, he started rizz me a lot and one day I asked him if we could go for a walk together, something a bit romantic after school ; so after school I saw him talking w his friends so I understood that he wouldnt come. I stayed at home and Dylan send me a message saying "Sorry I dont wanna have any grlfriend, its boring" LIKE WHAT THE ACTUAL FUCK. Now Im on vacation, and he continues firting w me by messages ;-;

Btw Im in crush w is bestfriend but Idk what to do bcz imagine seing that girl you "like" with your bestfriend like its awful but damn HOW TF IM SUPPOSED TO KNOW WHAT DYLAN FEELS NOW

I honestly think he loved me since the start but didnt wanted to screwed up, Idk maybe he just dont care at all, HOW AM I FUCKNG SUPPOSED TO KNOW RN.
