Anyone else can't imagine living with someone?

I think part of my happiness of being single is because I seem to have a very deep need to live alone. I'm very sensitive to other peoples' energy. There have been times I've had to sacrifice quite a bit to afford it - working 3 jobs, or moving cities because I couldn't afford to live alone anymore and I refused to have roommates - but I have always, always lived alone since I graduated college. While I've had serious relationships, I always put off the "moving in together" question. I resonate deeply with that Whoopie Goldberg quote of "I don't want someone living in my house!". Even as a kid I was fascinated by couples who were devoted to one another but didn't live together.

Spending a week in the same space? Lovely! Spending forever in the same space? Nope!

Anyone else have a NEED for their own living space? Do you think this plays into your satisfaction with being single?
