Is it normal if i’m not close to my dad’s side, but everyone else seems connected?

I’ve always been really close to my mom’s side of the family, but I’m only somewhat close to my grandmother and one of my uncles on my dad’s side. My cousins didn’t invite me to the gender reveal of their baby, and I rarely know what’s going on in their lives. They don’t exclude me from most large family functions, but I’m definitely not as close to them as the rest of them are to each other. When my cousin got married, I was invited, but I wasn’t involved in any way, really. I was very happy for my cousin, and they’re polite to me. My mother isn’t as close to them either, and my father spends most of his time with my mother’s side of the family, actually. I don’t think there’s anything really wrong with it, and it’s not as though they’re ever outright cruel to me. They’re my family, and I love them, but I wish I could be closer to them. I’m wondering if other people experience this and if I’m just making too much of it. I committed a social faux pas or two a few years ago, but I didn’t intend to offend them and tried to explain myself and apologize. I’m hoping that they aren’t polite to me because I’m their cousin but secretly dislike me. I know we can’t be close to everyone, but I feel left out sometimes, and they’re my family. I love them.
