Got Plans..........

Yeah I wouldn't just show up at his place without him confirming first. It could be he is honestly busy and just couldn't let you know, but if this happens a lot you need to let him know not to just leave you hanging. He should let you know.

How long has it been since you sent him a message?

He stood you up.

Here's my advice:

Forget him. For now. Move on with your life.

If he calls, here's what you say. Stay calm. Calmness is key.

"I like you, and we seem to have a lot in common. But I don't like how you handled things. I felt like you left me hanging. We had plans. I felt disrespected. So if you want to get together again, I need you to be more consistent and considerate of my time, okay?"

Note that this uses "I" statements. You don't say, "You disrespected me." Because he maybe didn't intend to disrespect you, and if you say "you disrespected me" it might seem like an attack and he'll get defensive. Instead, use a formula like this: "When you do A,B or C, I feel X,Y and Z." This shows a cause-and-effect, but avoids an attacking or blame mentality.

How he responds will tell you a lot about him. If he says, "I'm sorry, I didn't mean to disrespect you, I'll try to do better," he might be a good guy -- especially if he makes an effort to change. But if he says, "You stuck up brat, I got busy," he's a jerk.

Good luck.

When did you send him a message? Sometimes I get so caught up with work that I don't have time to talk for a few hours but I will respond eventually if I go to the restroom or something. I would not go around his place without a confirmation first.

That IS confusing. I wouldn't go to his house until he gives you a response back. send him a message saying if your still down for hanging out tonight call me later. He could also just be busy and hasn't had to time to respond to your message.
