To live alone or not to live alone?

This is the question that I am currently thinking about. As a single person the question must be asked - do I live alone? or do I share-house/flat with someone?

For the last 4 years I have lived 'in community', with the last 12 months being by myself in a flat (whilst still being 'in community'). I was alone but not alone.
And I loved it. I loved that there were people around that I could spend time with and be. (I'm not denying that it was hard to get used to the 4 years of fish-bowl living!!)
But I have moved away from that 'community' and landed in a completely foreign part of Sydney where I don't know anyone or anything.

And so the question is raised: Do I share or live alone? (obviously mainly applicable to the single adult person)

For all the hype of having 'alone time' or 'personal space' (of which I am largely guilty) I wonder whether this promotes a selfish and self-centred attitude to life.
Sure, there are difficult things about flatting with someone, but I think living with someone can make you a more gracious and understanding person.

Does living alone make you more selfish?

We were created relational but individuality is a prize of modern culture.
I wonder what the connection is between the individualistic push of society and the independant push of humanity from God - that is sin.
