Hi, everyone. This is one of the hardest areas to find a balanced, clear picture. We need to remember that God hates divorce (Malachi 2:16), but that He divorced Israel (Jeremiah 3:8).
The Malachi passage notes that God expects men treat their wives well. I think that a lot of the biblical mandate against divorce is to protect women and children, not to trap them in dangerous and harmful situations. I've seen marriages turn around, but not all.
The strongest Christians I know are not pastors. They are the women and men who have difficult (stubborn, mildly neurotic, selfish, occasionally cruel) spouses. So it's something that can, sometimes, work good in people's lives. It can also destroy your life. There are no easy answers except -- get out if there is real damage going on, or if the situation is clearly dangerous emotionally or physically.
