He doesn’t talk to me enough?

i met this guy online and he kept saying how much he was interested in getting to know me , so i gave him my number after 2 days. now he doesn’t really respond and he’s active online but doesn’t talk to me. so i tried to return his energy and flirt eith him , like how he did me constantly when we first met, but he told me he wanted to “move slow” and started ignoring me.. i waited 2 days and told him i didn’t want to be friends anymore and blocked him before he could respond. why did he do that? he basically pestered me until i gave in then made me wait?
