I feel bad... help😭

So my boyfriend and I have been together almost 7 months now... Friday was a fb game and pep band had to play the first half. He came at halftime cuz I said I'd watch the rest with him. Then my mom texted me saying that I had to leave and he came to the game for me so he watched it with a couple friends but I still felt bad... I told mom and she felt bad so we arranged something for today. We were gunna go bowling and it was gunna be the first time he was actually gunna hang out with my family... Well my mom didn't want to today so I had to tell him I couldn't and I feel super bad! I know there's nothing I could've done but still I feel really shitty about it! Anyone have ideas on what to do to make it up to him? I wanted to surprise him at a golf game he has Thursday(our 7 months) but it's an away game and idk where he plays or how I'd get there... I have pep band Friday again and I know I'm staying the entire time but I don't want him to think I'm gunna leave early again and I'm sure his parents are mad at me too...
