Grounds for divorce
If a man is lying to a woman before they get married and she catches him in the affair, is that biblical grounds for divorce? The lies get worse and he's on drugs. He won't pay bills or provide food and necessities for his family. She begs for him to get help and he refuses. She leaves a few times for a night to try to get him to change, but he wouldn't. I'm already divorced, just really struggling .
To me, your words reflect unfaithfulness (Matthew 19:9) and desertion (1 Corinthians 7:15) on the part of the man. Such actions are biblical grounds for divorce.
As this question and answer forum is not suited to provide the spiritual care and support you need, I encourage you to contact your pastor and speak to him. If, for whatever reason, you do not see yourself being able to speak to your pastor about this, consider using the counseling resources available from Christian Family Solutions, a WELS-affiliated ministry. In addition to face-to-face counseling, they also offer video counseling. God bless you.
