Admitting drug addiction or alcoholism before the marriage in order to prevent a divorce?

It may have been beneficial for someone debilitated by drugs or alcohol to stay in a marriage, even a loveless one, in order to receive care and have a roof over one’s head. Even today many woman stay in loveless marriages to functioning alcoholics for this reason, and many men abide this status quo because it is easier and less expensive than divorcing. This routine may not be appealing to third parties looking in; however, it works for the parties involved.
