Judaism has the most liberal views on divorce of any major religion. Not all Jews mirror this attitude. Traditional Jewish communities have frowned on divorce, but the Torah makes it readily available.
I know many Christians who are stuck in loveless marriages but feel a need to stick things out. They do this for either religious reasons (that only adultery is grounds for divorce, which seems to be the teaching of Jesus) or for the sake of the kids.
Whenever I hear kids talk about their parent’s bad marriage, they usually wish their parents divorced out of such horror or were glad they did.
If you’re determined to stick out your marriage till death do you part and your marriage turns irretrievably bad, you’re going to get through your tough times by fantasizing that your spouse drops dead. And your kids are going to pick that up. It’s not good for kids to grow up in homes where the parents don’t love each other. It gives them no good example for their own marriages. It warps them.
