WHAT DID I DO WRONG

i’ve been taking to this guy ever since around february time and the other night we were joking/“flirting” around sending ;) and stuff now he’s literally just ghosting me like what did i do wrong he even purposely didn’t send me streaks yesterday just so i wouldn’t snap him i’m trying to get over him but i can’t without knowing if i hurt he feelings in any way but if i ask him out of the blue he’ll know that i have feelings for him and it’ll all go pear-shaped and i don’t know what to do bcos i can’t get it out of my head
