compu - the answer to your question is: it doesn't make any difference. it is illegal for people of different sexes who are not related (marriage / family) to share accommodation ;o)

by the way... why would a woman want to live with a guy without getting married?
- she's missing out on a ring and other perks that wifes get!
- she still does all the work that a wife would, again... without the perks that wife would have
- and finally there is this risk she'd take here...
... plus a guy will no see a reason to marry her since she's already doing the job!
ha ha ha just being cheeky ;o)
