Messy relationship with this guy- any advice?

My good friend and I developed feelings for one another. We discussed it and I wanted to be a lot more serious than he is "able" to right now. Things got messy, to say the least. We decided to take a break and not really talk and re-evaluate later on. Because of that, a lot of our conversation was via text.
He said I was really intense and didn't have the energy to deal with that, when I asked if we could get together.
He deleted me from Snapchat and went to a concert I told him about and we were going to go together without me, without mentioning it to me at all.
I told him I thought he wasn't treating me nicely and I didn't even want to be friends, let alone be in a relationship. I've only been nice and considerate throughout this and it felt like he was just being harsh.
He told me I take everything he does personally and that's all he had to say.
I was feeling really emotional and wrote a whole long thing explaining my feelings. The next morning I wrote a more dignified message just apologizing about the novel I wrote the night before... and that I'm realizing through this that I'm not even ready myself for a relationship and this showed me I have a lot to work on.

He never responded. It's been a week. I deleted his number for fear I'd just keep contacting him. I also deleted him from other social media because it just was too much. I needed to clear my head- this was all making me crazy.

Now I miss him and wonder what's going on in his head. Why he hasn't even bothered contacting me. If he misses me. If he thinks there's still potential for us. If he thinks about me at all. If he just thinks I'm crazy now...
