I'm not condemning you, but I think the mindset there is if we remarry, we will be living in adultery, and that would be the problem, "practicing sin" as a lifestyle.
As I've mentioned before, I'm just not sure about this situation. Seems so harsh to not be able to remarry in an abusive situation, but at the same time, the bible "seems" to indicate that is how it is.
I would ask one to consider the fact Jesus did mention, in the days of Noah, in spite of the fact it was meant to be a one time forever marriage, still, a letter of divorce was all that was needed, and they were allowed that divorce and remarriage because of the hardness of their hearts. Do we not clearly have hardness of the hearts today? And if they were meant to be with one spouse all their lives but were not back then, did they not commit adultery then as well? Yet remarriage was allowed and they were not condemned to hell because of it.
Those are some of the reasons, something doesn't seem right about the general interpretation of all this.
