I NEED ADVICE!!!! 😞😥

Ok so about a year ago me and my boyfriend started dating,but a couple of weeks after we started dating he moved to a different state! But we never officially broke up and he could  never afford his own phone 😕 I know what your probably wondering, why didn't we break up? Well he never told me he was moving! One day he was just gone! Anyway, after that me and him never got back in touch, but a year later( this summer) I get a follow request on Instagram from him and we started talking, and he said that he's  moving back and going to my school for senior year, so we get back to get back together!! We started dating again last month anf a couple days ago I try texting him but he won't text back, so i Direct message him on Instagram and it says that he reads the messages I sent him but he just Ignores my message! Ever since last week he just  doesn't text me back, I don't know what to do! Plzz I need advice
