Maybe it is best to sit down with her and and try to identify (together) what happened in the last five years which caused you relationship to diminish. Many women get new jobs or responsibilities. Are you sure THIS is the reason for her wanting to feel independent? Does she feel that you are crowding her? Does she feel that you are not receptive to her needs? Are you treating her the same as you did when you first got married 11 years ago? These are critical areas that must be explored if you want to make this marraige work. Remember, you can't convince her of anything unless you can first identify the foundation of the problem, and then, you "convince" someone of your good intentions by your actions.
Since you have identified yourself specifically as "Christian" perhaps you are trying to force a role and lifestyle on your wife that does not meet her own needs.
No she cannot get a scriptural divorce after she has already taken back her husband. They are "one flesh" again so if she gets a legal divorce and marries someone else, she commits adultery. If she wanted a scriptural divorce, she could've divorced him after he committed adultery and not "forgiven" him and taken him back.
You could, but it might not work.
No way! She gets to keep it.
IF she feels she made a mistake.
I think you can't file a divorce, I mean there's no valid reason why you will divorce a good wife.
The car will be marital property and will be awarded to one of you in the divorce.
When a husband wants to keep his family and still have his mistress, then yes, the wife has every right to file for divorce.
You can STILL get divorced.
Have him get a divorce. Don't marry a who is already married. It is going to be trouble for you.
Then the husband should move out.
No. In Western countries a spouse cannot force their spouse to stay married. The divorce can proceed even if one party wants to stay married.
Every situation is different - my mother left the house.
