Observe the camaraderie of war.
Soldiers are brothers in arms.
They save each other. They died for each other.
Their bonds are strong.
The bonds between partners, couples, spouses should be of the same or greater strength and priority. They are bonds of friendship.
If the bonds between you and your partner are not as strong as those with your friends, the relationship with you partner will be jeopardised.
And if relationships with your friends are strong, then that with your partner will be better. And your life will blossom.
