Help?

I don’t know what to do I’ve been dating my bf for about a month now. But since last week he’s been ignoring me after I told him I didn’t like to be ignored. Now I have all these thoughts running in my head and I sent him a paragraph of how I felt and all he said was “what are you talking about” I don’t know what to do anymore. Can anyone give me advice? I don’t have anyone to talk to about this.
