Each of us have our own personality and drive.
Having a family wouldn't make me happy(it would have given me nightmares) because I'd be creating problems that I never needed to create. I would have brought someone into the world that I know is gonna have more suffering than pleasure.
To me relationships can be summed up in one word: Chaos.
I once came close to marriage in my very early 30's, but I sabotaged it because I knew I was giving up freedom and I knew that I would make a lousy husband and father because of my extreme views. And most importantly I knew that I would never be able to retire and I would be stuck in a world ruled by emotions.
My personality is that of a loner, I never hugged my mother, I don't show emotions. When I started meditating in my mid 30's for long hours I realized that I could turn off completely from the world, desire, impulse, pain and that's when I found the freedom I was really looking for.
I look around at the world and see most people causing their own problems. They eat, spend, love, cry and want too much, they keep riding a roller coaster over and over. I stepped off and waved them goodbye as I can't see a point in this madness.
