Pls give advice, sad bean here

My boyfriend and I have been officially dating for 3 months. I know, it doesn’t seem like very long, but we’ve been « together » for about 6 months. He and I get along well and what not too, and when we argue I forgive him quickly (he’s quite a bit slower at doing so but by the end of the day usually we’re good)... So lately he’s been a bit distant. I play a sport and he, at he beginning of the season, said he’d come to my games. We’ve played about 11 and he’s been to about one game. he’s been invited every time but something always comes up. He has okay reasons but Id prefer him to stop saying he’s going to come and then he doesn’t. And he rarely seems to actually do what he said he was going to is this normal? Am I overreacting? I’m just sad
