does anyone have guy advice? i'm 14

so i have this crush on this guy and he seemed interested too he's always make eye contact flirtingly and stare and two months ago my friend let it slip that i liked him, and he said "i kinda like her too i just want to get to know her better" but after that idk why i started avoiding him and he kept chasing me and now it's winter break and i added him on snapchat. his friend said he left everyone on read but i started noticing that he never left me on read, until he seemed to realize that i left HaiM on read but. y ACCIDENT. so now he is leaving me on read. what should i do?
