Is it normal that i don’t feel emotional attachment to friends or family?

I’ve never felt much emotional attachment to friends or family members aside from the very immediate relatives who I grew up living with (parents and sister) and I never really felt that it was a great loss when one of them died. I don’t really see my friends as more than acquaintances either, I hang out with them purely as someone to talk to and I stopped visiting almost all of my family when I moved out of my parents house. I do wish I had real friends but I find it hard to sit there and pretend.
