When Jacob was hoping for a get-back attack from Esau, he had let go of the anger emotions; sanguine spouses are quick to forgive and are very apologetic in nature. Meaning that they are quick to accept their faults and apologize for them, though it is unlikely not to find them in such a fault again because of their instinctive nature.
Sanguine spouses are emotionally expressive; this helps them to easily process their anger, hurt, or trauma and forgive readily. Their spouse needs to learn this great attribute from them as they could easily be frustrated with spouses who internalizes emotions or keeps malice.
