I've never thought "Marriage is the center of [my] life." nor relationships in general. I'm a male though. I suppose for women it's much more common to consider marriage & childbirth as the "center" of life.

For me, it's being around friends. But I've never explicitly thought "Friendship is the center of my life."

I think the "center of one's life" simply means "number one priority or goal" and that it changes depending on one's focus. For a while, learning to become a developer was the center of my life, and then getting a job as a programmer.

I suppose I don't have one now. I suppose it's learning a new skillset and getting back to working (laid off recently).
