Did my boyfriend dump me without telling me?

ok so, abour 3 weeks ago me and my bf was chatting and he said he was too tired to stay up and talk. so, i kinda ignored what he said and never responded . 2 weeks later i got a text from him from a weird number saying "hey whats good with you" i didnt respond because i didnt know who number it was, a day later he texed me again saying "hey, are you mad?" i didnt respond but i did call him form blocked just to find out as to ehy he was not texting me from his phone, and he did answer but i hung up when he answered cuz i was only checkin up on him.since his last text i have not heard from him. i called his phone and it says its not accepting calls. what gives?
