I NEED HELP!!!❤️❤️

So I have had a crush on this boy for a while, I have known him for six years I think and I have liked him for two... he hints sometimes that he likes me , he really acts like he likes me, lol he’ll tell me he likes my outfit or one time he gave me his jacket. Me and his sister are friends and we had a sleepover like...2 weeks ago and I finally got the courage to tell her. Now, he won’t even talk to me.😭 What’s going on?!?! Did she tell him?!? I am so worried he will never talk to me again! WILL HE EVER TALK TO ME AGAIN?!? I am freaking out here!!!
