Good decision, a good friend of mine actually did have a female friend stay with him and his wife (him and his wife are black, and the female friend was white).Viola was your wife's college roommate and she recently got hired by a law firm in your city. Your figured she could stay with you for a month or 2 until she could find a place she could afford.
Decline - POLITELY - and walk AWAY.
They're BOTH attorneys so it would NOT end well for you.
He told me that his wife's friend was very attractive, nice person, but noticed that she would greet him with a "kiss on the lips" sometimes when the wife wasn't around. Although, it never went further than the brief "kiss greeting" it did have him thinking about whether she was just being "friendly" or wanted more?
