I never realized how comfortable I was alone until I WAS alone. And I grew irritated with the people around me telling me I was missing something from my life. They couldn't grasp that the cats and I didn't need anyone else. We were fine.
I even bought my house with zero intent of anyone else coming into the picture. Just enough space for us. People told me I was crazy. "What if you get married?" I told them I was happy alone. They told me I needed therapy.
As it turns out, I HAVE ended up married, but it worked out in a weird way. Both of us enjoy our time in quiet and separate but together (if that makes sense). We do our own things - no need to step on each other or invade space. Of course, that seems weird to people, too. (Oh, and the house worked just fine)
