There's a tremendous difference between alone and lonely. You could be lonely in a group of people. I like being alone. I like eating by myself. I go home at night and just watch a movie or hang out with my dog. I have to exert myself and really say oh God I've got to see my friends 'cause I'm too content being by myself.
I really enjoy being single again. I spent a lot of time in a relationship and the nearer we came to the end the more difficult it got. You don't see things clearly as long as you're still involved.
