What are acceptable reasons for divorce within the Protestant Churches?
There are no hard and fast stances that are among all Protestants. And in many cases it is a case by case basis. I say this because in some churches, divorce is not acceptable under any circumstances, while other churches are more lenient. What my pastor explained is that divorce is only acceptable in the case where one party has not fulfilled their vows. For instance, if a spouse is unfaithful, or mentally or physically abusive to the other spouse or the kids, those are valid grounds for divorce.
