Should I be mad at my boyfriend for this?

So I moved into college this morning (I'm a freshman). My boyfriend is a grade below me and he offered to me 2 or so weeks ago that he could come help me move in and I thought it was so sweet of him because I hadn't even asked. Anyway, last night he decided to go out with his friends an hour away (which is fine ofc) and get absolutely shitfaced to the point where he had to sleepover one of their houses and I still haven't heard from him today and it's almost 12 in the afternoon. I'm all done with moving in but I could've used his help and I'm a little upset that he just blew this off like it was totally nothing and that I still haven't heard from him today. Should I be mad or what? 😕
