Teen boy trouble

So i had this really good guy friend. and we were texting one day and he asked me who i liked. i told him that i liked him and he said he didn’t want to get played or hurt. and afterwards we talked for a bit and then i said bye. it has been a little over a month and he has been ignoring me completely until today. when he finally talked to me. and he was flirting with me and was standing super close to me. and i was like what the heck bc he hasn’t been talking to me for a long time. what should i do and what does this mean?
