I gotcha! I wouldn't get too upset about it. He's a single man so it didn't cross his mind to inform you of his weekend plans. It would have been nice but it is clear that he values his freedom and is fitting you into his life on his terms. Is he an alpha? Dial back the emotional investment, give him space, and let him get ahead of you in his feelings. If he's interested, and you give him space, it'll happen. Next time you see him, be just as warm, flirty, and engaging as you have been, but when he's not around, detach. Even if you don't have other men to date, make him think you do. I'd be unavailable next time and take myself on a date if I have to. Make him miss you. It's hard for us to control our emotional investment when we're super into someone but quality men are used to every woman longing for them. Once you create a longing and sense of urgency in them (through actions) they are inspired to commit and they appreciate it. This could be a good one just don't get ahead of him emotionally. Turn the convention he's used to on its head. If he's interested he ain't going nowhere. If he's not, oh well. There is nothing so rare and magical about this man that he can't be replaced. It's taken me over a decade to understand this. Trust in your awesomeness and this man, or the next one, will be begging you for exclusivity.
