I have several good friends who seem born to coupledom. They are happiest when they are in a pair. I see them glow with a significant other in their life. It makes me happy they are so happy.
However, even when I look at them, I see where I would chaffe under the same circumstances. I am not made for that. There is a tranquility that has come with accepting this fact. The letting go of the struggle to find a soulmate is completely liberating.
