When is it weird to talk to a guy?

So this guy just came up in my mind and we had some pretty good conversations and everything. I haven’t spoken to him in a little over a year. Is it weird to try and get his attention again as he did play me a little dirty as we were supposed to me and I was heading to see him and then he said he had a hockey game and couldn’t see me. He didn’t even invite me so, but I just started thinking about him again. Is that weird? Or should I just move on?
