I don't know what to do

So me and this guy have been friends for a little over 2 years and people keep thinking we are dating and we are not. Here's the issue i told him i need a break from him to juat gather my thoughts. I've told him this in the past he never freaked out tho. This time he did we got in a huge argument and i don't like it. I'm worried about him he won't text me and i'm scared. His sister told me that he was tearing up talking about it. It hurt him that bad. I feel like a complete idoit and i am a complete idoit i don't know what do. Someone tell me what to do.
