Boyfriend of 1.5 years dumped me but hasn't blocked. Will he ever come back after telling me to stay away from him?

My boyfriend of 1.5 years dumped me and hasn't texted me for 2 days. One of his last messages was 'if you truly care about me stay away from me'. I said I did and he said he didn't want to block me so I shouldn't force him to and I didn't message him. He also told me to only message him in urgent situations. I asked him about the situations and he said ( sickness / accident / violence ). Why would he say that? Does he want to see me in pain? And why doesn't he block me if he dumped me in the first place? I have soo many questions...
