Many marriages have been destroyed by siblings & parents with wrong marital values, understanding, decorum or appropriate approach. Other times because they do not understand what you have been blessed with.
The same people helping to create tension in your home may be because they desire for you, the status they hold. It may be because they are unhappy with how you are doing.
Be careful & prayerful.
Be protective of your marriage & home because after all is said and done, the same people will come back to mock you when they succeed in destroying your home.
Family is important but family needs first to be good to you.
