Being alone is a very peaceful life. Take it from someone who has been alone (by choice) for 29 years now. And, for the 10 years leading up to my divorce, I really had no relationship with my wife. I tell you this not for sympathy but to make the point that truly, all we have is ourself. We all need to be comfortable with ourselves, first and foremost.
