<human>: Had plans tonight to go on a walk and then play wow with bf right. It turns into lets play volleyball instead. I'm just getting off work and physical activity didn't appeal to me, so I said go play volleyball and just let me know when you are done, so I be ready to play. He says okay I def don't want to play past 1am. (Later he tells me that him saying that was purely hypothetical) I said thats cool just let me know. 

I emphasize the importance of this to the point where he got irritated and said I will let you know 30 minutes before. Well then its 2am. He says his phones dies. Thats fine. I tell him I'm not happy that its 2, but I drop it to ask how it was. We had a little quick chit chat about his night. He sends me a message about 15 minutes later saying are we gonna play. At that point I was finishing up the thing I was doing and headed to the bathroom. It takes me 5 minutes to respond. And I said well yeah that was the plan. He goes "k yeah well I'm already in bed". And then he goes I wish you really could've came tonight it would have been fun.

Is it wrong for me to be upset that he couldn't wait 5 minutes after I have been waiting much longer? And that he shifted me and our plans?Because when I said that we were going to talk about it tomorrow because I'm upset, he got mad at me. For some reason I could not drop it until tomorrow. I realize my mistake in that. Just was extra upset about it, because something similar happened yesterday. Where a workout (he usually only takes 30 minutes to work out) and checking on something for his class turned into 2 and a half hours of me sitting and 
getting no response from him.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Boyfriend forgets and puts off plans with me, expects me to wait around, but then can't wait for me.
