How does Sagittarius react against infidelity?

Deadly understanding

Understanding as few, Sagittarius always rescue the positive aspects of a relationship.
Therefore, even when it is over, they will seek to maintain a friendly relationship with their partners.
Often devote more energy to preserve the cordiality than the relationship itself, although this may seem unloving.
When Scorpio really want to achieve stability in a link they should – at least once in a while – fully give in.
They are not possessive, so if they surprise in flagrante their spouse, they may not claim anything.
Of course internally they will be very disappointed.
But the sense of freedom that encourage them is above all.
Suggestion: Sagittarius should be aware that your partners may need more demonstrations of affection and even a dose of jealousy to feel loved.
