How soon should a man and woman live together?

He wants to live with but a very close male friend of mine doesn't think I should go that route. Instead he thinks its better if he lives with me instead. He thinks the guy is rushing a relationship when I'm just getting back into looking for Mr. Right! This new man is a pleasure to be around and doesn't let his status downplay our getting to know each other. He knows where I work and he knows why I'm still there. He doesn't judge me or look down upon me as not being on his level. He knows what kind of woman I am and right now I have to do what I'm doing for my own personal gain. Some men judge you for all sorts of reasons. I'm just glad the men I'm dealing with are on my side..
