I know there has been discussion on this topic already but it seemed conflicted. My daughters and I escaped horrific domestic violence that was physical, mental, and sexual.He also had numerous affairs. We actually are still in hiding as he still after four years stalks, harasses, and threatens.
His parental rights were terminated by the state. He is no longer legally considered the father of my children. I constantly question my choices and feel like Im going to do something to upset God. It almost feels like a barage of attacks. My questions are as follows:
1. Is divorce forgiven by God in this situation.
2. Someday could I remarry?
3. Is it normal to feel lile Im constantly failing God or is it a spiritual attack? How do you differentiate between the two?
Please be kind but direct in truth please.
