Why didn’t he wish me happy birthday?

This guy we I use to speak to everyday and got close to didn’t say happy birthday to me yesterday and I feel down and he doesn’t care. We kinda stopped talking as we had a mini argument well miss understanding. He just ignored me that one day 2 weeks ago due to this miss understanding! However he watched all stories and knew it was my birthday and didn’t say nothing. I did friendzone him kind of but still it hurts. I thought we were closer than that. And why not just block me if you’re completely done.
