Why do relatives from the father’s side seem less supportive compared to the mother’s side?

I recently attended a family funeral, and it brought up some old frustrations. Relatives from my dad’s side basically disappeared after he passed away years ago. When they saw me at the funeral, the first thing they said was, 'Namukula Mwebana! Ninshi baninenu bamitalwisha kulifwe balupwa benu?' (“You’ve grown, why did your mother distance you from us, your family?”). Like Seriously? You haven’t seen or checked on us in almost two decades, and your first move is to discredit my mom? She wasn’t perfect, but she worked really hard to raise us.

Before I could even process that, another aunt hit me with a barrage of questions, "What are you doing now? Where are you working? Are you married?” When I said no, she responded, “Yama, what are you waiting for?” 🤦‍♂️ Anyway...😁

After my dad died, none of his relatives ever visited us (they didn’t like mom). He was the breadwinner, and life became really tough for us. Occasionally, we’d run into these relatives in town, and they’d say things like, “Mwebana imwe, tamu tandala!” (“You children don’t visit!”). We used to reach out to them, but it never led anywhere. On the other hand, relatives from my mom’s side didn’t have much, but they showed they cared through their actions.

This got me thinking. Is it just me, or is this a common experience? From what I’ve seen with friends raised by single moms, relatives from the father’s side often seem less supportive. Is it a cultural thing, or are fake relatives just on both sides, and the mother’s side just has better PR? 😅
