I’m just speculating here based on my own experience, but I wonder if part of it is also something subtle in your attitude that others pick up on.

When I met the man who is now my husband, I wasn’t even looking for a relationship. I was just enjoying my life, exploring new hobbies, and was in a good place mentally – that is, I was fine if I ended up single for the rest of my life.

I imagine married people also tend to be in a similar frame of mind where they aren’t looking for a relationship, and maybe there’s a confidence that comes out of that that is attractive to others.
