Why is it bugging me so much?!

I had been dating this guy for a while & there were a few red flags but I still liked him.... we are both under stress for a number of reasons but I also felt he wasn't making the time to talk etc I reached out asking if we cud talk things through & also where I stood with him but he kept saying he doesn't have the time & it'll have to wait.

I know i need to walk away... but he kinda got under my skin as he refuses to say what he wants....

I blocked him for a while & then got back in touch just to say hello... He's pissed off that i blocked him & said he didn't have time for it esp when he doesn't talk to anyone let alone me...

Again i know i need to walk away but hate the fact he can't say to me that he doesn't have time or he's seeing someone else or whatever is the reason why he can't talk to me...

Its really irritating... help!
