one thing to add, I am not against all divorce. There are many legitimate times to dissolve a marriage. And cheating especially when coupled with physical or mental abuse is an appropriate time for divorce.
Getting to the point of divorce is a process which takes time often many years of not cherishing and loving one’s spouse. There will be mistakes and even cheating, which can amount to an acceptable point for divorce, but rarely do these events happen overnight or in a total vacuum.
