I'll give you the short version. He has trust and anger issues that are either related to his divorce or something in his past that he's never bothered to resolve. You need to move on, because frankly he needs counseling and isn't likely to get it until he's ready to do something.
He's pretty much displaying typical bitter divorcee behavior.
As for guys and space. All people need space, but space doesn't typically mean don't talk to me at all, it typically means a few hours, maybe a day. Not days, not weeks, not don't bother me until I come calling for you. Space means he needs time to calm down, because he feels that he cannot mentally function while he's so emotionally charged.
Likely you should ditch him now, because if you're having these problems when you're dating and seeing each other on an irregular basis, he's only going to get worse. Save your dignity, time, and emotions for someone deserving of them and willing to accept them as-is.
"Well, then," the Cat went on, "you see a dog growls when it's angry, and wags its tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad."
