Spiritual mathematics is unique.
When Christ Yeshua is invited to join a couplehood, 1 + 1 + 1 = 1
The equation is simplified by knowing that He is already in us and that a man and a woman are 1 flesh.
Jesus said regarding committed relationships:
Therefore what God has joined together, let no man separate."
When a couplehood invites Christ Yeshua to join them and because He politely honors our gift of free will, ALWAYS answer His knocking.
