Hereorthere, we need to define last resort:
1) A woman gets beaten by her husband. She slowly saw signs of violence in him but ignored it during engagement. Now it escalated to physical violence. Gone.
2) Man or woman regularly beats up kid or spouse (and I don’t mean a potch). Gone.
4) Man or woman is addicted to some substance (alcohol, drugs etc) and doesn’t want to change. Gone.
5) Man or woman lies about something major before marriage. Gone.
In which of these cases should the man or woman stay with the spouse?
