Emotions are part of human make-up, but melancholy spouses are not emotionally expressive, unlike the sanguine or better still, the choleric spouses. Jacob exhibited how melancholy can internalize emotions when he internalized the anger and frustration emotions that could have emanated from how Laban changed his wages ten times and deceived him into marrying his elder daughter instead of the younger one, making him to serve seven more years for his true love.
The partner of a melancholy person needs to trust God to be sensitive as to what emotion his melancholic partner feels per time since he/she is not emotionally expressive, thereby helping him/her to be less resentful.
