Why Pisces is unfaithful?

Sensitive and easily hurt, Pisces is only cheating if he does not feel protected in a relationship.
Pisces strongly merges in his relationships, to the point that he loses his own identity.
If he is unable to express his emotional discomforts, his fragile nature will lead him to change partners.
Erotic and sensual, he will seek to enjoy all the pleasures that your body and mind allows him, which, in its most negative, does not allow him to discriminate whom he relates.
Tip: Treat him with tenderness.
