AIO to him not updating about plans?

I (19F) have been dating my bf (23M) and we’ve been long term since high-school. Anyways long story short, we’ve had COUNTLESS conversations about how irritated I get when I have to FIND OUT something that he has to do from OTHER PEOPLE like his friends or mine or his family. Why can’t he tell me himself? I’ll give a scenario. He is a volleyball player and I love to watch his games, I think for the past 5 games now I found out through other people that he had a game coming up and I didn’t know. Just today my friend asked, “hey are you gonna watch (bfs) game tomorrow?” I replied “what game” and she sent me a facebook post of the team posting they have a game coming. I got pissed because this exact same thing happened last week where he had plans to play pickleball with one of his buddies and I found out through his friends making a joke that he’s gonna beat him 15-0 tomorrow and I should watch to see him get destroyed. Another time he had plans with his family to go out to this place on this specific day that I also made plans with him and when I was with his family for dinner and told them we were gonna have this little road trip, they said oh but we’re going to this place blah blah and i felt so humiliated. Everytime I then confront him after he goes “oh yea sorry i forgot to tell u i had this” “what i thought u already knew” “well I figured you already heard it from my cousin so I didn’t have to tell you” like would it hurt to actually get the news from my boyfriend himself??? Anyways I brought up a huge fight and I’ve been yelling at him saying he doesn’t think I’m important enough to update about his plans and I need to know am I overreacting for being so mad at this seemingly small issue?
