<human>: This is why we can't have nice things. I have a crush on this guy, we're in the same class together for grad school. We've made plans to study before, and despite my best intentions not to, I usually initiated such sessions. Supposed to study together today, but 10 minutes before hand, after I asked where he wanted to meet, he said he had to go sign a lease and wouldn't be back at all today, with no mention of making plans for later on. My natural inclination is to be done and say nothing, because it's just rude to do that right before. But is this just general lack of awareness, or is it blowing me off? I don't want it to be him blowing me off, but I'd like some honesty. We've flirted before and he's come over to my house with a mutual friends and had a few beers before... so I don't know what I'm missing.

Can you give me the gist of the text in a nutshell?
<bot>: boy canceled plans at last minute, is this flakiness his lack of interest/ blowing me off, or is this just a guy thing?
