Depends on the context of the relationship. How does she know the husband? If they regularly cross paths at work, for instance, I wouldn't think a thing of her. If she's seeking him out when their relationship would otherwise just be in-passing, I'd assume the witch had some mighty big testicles to be so nonchalant about her motives and "cold shoulder" would be an understatement.

Had something like this recently. DH was his normal friendly self to the teller at the bank. He goes in frequently and would chat with her. She was living with her BF about 1 mile from us. Next thing I know, she has friended him on facebook. Shortly after that she is sending him private messages and instant messaging him late at night about breaking up with her boyfriend, needs a place to live, etc. while he was working on his homework. I put my foot down and made it clear that this had crossed the line, this was disrespectful to myself and his children and this was not a behavior that an ethical person would engage in (I also threw in how would he feel if I was getting calls from my "male friend at work".) He instantly de-friended her. I also make sure I do all the banking these days
