Not close with extended family

I’m just curious about other peoples’ family dynamics. My aunts and uncles on my dad’s side are the kind of people I don’t see or interact with unless there’s a funeral. And even in the past few years, I haven’t been to those. My parents kind of “manage” our relationship and pass information back and forth. I feel guilty about this, and I have one aunt who will occasionally text or call once every 2 years or so, but I can’t say that anyone else makes effort…and I don’t exactly either. To give some context on the awkwardness I think of when I think of this side of the family, I was visiting their state and saw my uncle in the mall. He looked right at me and kept walking by as if I were a stranger. I was probably 16 at the time. 34 now.

My dad really wants me to be the one to tell his side about the pregnancy, but I haven’t spoken to them in years. I don’t feel close to any of them, and being related by blood doesn’t mean much to me. They are honestly some of the last people I think about when I picture my baby coming into the family.

I’m not looking for advice on what to do, I’m just wondering what other families are like and if anyone else has similar feelings. Or how it went once baby was born?
