For me, i felt like that also when I was 35. I didnt want my family to be in my life since I didnt feel good around them.

Now at 50, I have again connected to some of them. Because you get back to those feelings that life is not endless and you start to think about that you will one day not be here anymore. And its nicer if that happens when you have made peace with at least some of those people.

Tldr, age made me think different at different stages. Maybe it happens for others as well. :)
