Truly speaking, a marriage without a proper channel of communication is likely to crumble, communication is the bedrock of every marriage, even during courtship or before partner meet, there is this closeness that become initiated as they begin to communicate, through communicate individual differences could be seen, characters are unveiled etc. Another thing is that there is no perfect marriage there are always flaws, misunderstanding but as the couple live together they begin to understand each other. Thanks for the invite.
