A wife should have no contact or communication with another man that she would not want her husband to know about.

This does not mean that you cannot male friends it means that when you do you conduct yourself properly at all times and do not say or do things that you would not want your husband to hear or know about.
There should never be a time when you don’t want to tell your husband about something you have done or said, you should never give him a reason to doubt your faithfulness.
If he does not permit a friendship with a certain male then you should respect his wishes.
