Guy cancelling our date an hour and a half beforehand

I don’t even need advice on the situation but I’m ranting because I need to know if the dating scene is absolutely shit for everyone at the moment???

I was on Hinge for a while and a guys I’ve been friendly with since I was a teenager slid in and we chatted for a bit and then it fizzled out. We’ve made out before at parties and always flirted on and off over the years but I never really took it seriously, just some banter and I really only saw him as a friend. A few weeks later he slides into my dms on Instagram and we start talking again and kind of randomly starts talking about how he really wants to give us a shot and would I be open to dating him and seeing where it goes. I was really surprised and obviously asked him why the sudden change of heart and he gave me pretty valid reasons.

So on Monday we arranged to go on a date on Saturday (today). We spoke last night and he picked the time and the place. We spoke again this morning and then at 1pm we texts me saying that all his friends are going day drinking so he’s going to go and he’ll have to forgo our plans but we should pick another time to reschedule. Bare in mind we’re meant to meet at 3pm???? I’m actually mind boggled at how rude it is and I’m so angry as I myself turned down plans this afternoon because I already agreed to meet him! I just don’t even understand how he went from “please give me a chance” to “something betters come up let’s reschedule”. Also for context we’re both 24.
