Broke no contact and dumper wants space?

I am dumped last month, and I blocked him afterwards but I still struggle to function like a normal human everyday.

I reached out yesterday as I was totally going insane thinking about him. Yet he told me to respect his boundaries and ask for space as everytime I message him, he got reminded of guilt and shame?

I don't understand and I'm still trying to process things. If he truly feels guilty shouldn't he help me get through this by showing more care, instead of asking space and said that I am disrespectful?
