For those who have difficulty being alone, why do you think that is?

I have had a live-in partner almost continuously since I was a junior in college. There have been times when I paid little attention to my partner, but just knowing she was there in the house made a huge difference.

I’m not sure what is going on here, though. Is it that I feel loved or lovable? Is it companionship? Is it knowing someone is there in case I get in trouble? Is it knowing someone will be checking up on me? Is it having someone to make love to? Is it feeling like I’m not a person if I don’t have a partner?

I really don’t know. If there are others of you in this situation or like me, what are your thoughts on why you have difficulty being alone for any serious length of time?
