I need help regarding a guy i just met, i m 20F and he is 20M

So i met this guy online and he was all into me but i don’t know what happen now, he says that i m the only person he is talking the most in his life but in context he follows 441 girls on insta and there are only 10 guys, and he has private account as well whom. Moreover after our first meet up, he planned another as well but no calls and no regular talking and whenever he comes to meet me all his sc and insta is hidden with notifications off and he lies a lot as well He told me he doesn’t use it . Its been just 30 days So what exactly he wants from me? I am really confused cuz i was the genuine one
