Choleric are often attracted to partners who are good listeners, peace-loving and have good social skills. Aside of the privilege information Rebecca has about her children’s destinies, I personally belief that she most have been especially drawn to Jacob’s plain and homely nature.
A choleric spouse needs to frequently works on his/her esteem so as not to become overly possessive, angry or violent in a marital relationship especially where things are not done in his/her way.
