Crush is hot and cold

He texts me throughout the day but around 5 pm he goes MIA but still posts on sc and views my story and then comes back and says sorry I was busy. But he was on sc? Then it happened again but this time he said sorry I was doing this and that and I said but u were on sc lol and he said “I didn’t mean to look like that does it bother u” of course I said no I didn’t want to seem crazy he’s not even my bf lol and then he asked if I was sure and I said yes and he didn’t reply to me throughout the whole day after that but kept posting stuff on his social media. He texted me this morning with “Hi” any opinions? Does he even like me? What is he playing at do I just stop talking to him all ? What do I do?
