One way a Submissive wife can show respect to her husband is to seek his approval before she arranges any social events. Even if this is unnecessary it will show him you value his support and put his wishes before that of your friends.

Should your husband not approve of a social event then respect his wishes and trust he will have a valid reason for not wanting you to go.

Don't put friends before your husband

You are married, so it is now MR before Sister!
