Mania,
I can't offer any additional advice, but I sure hope this woman gets the help she needs and is able to get out. I'm no expert, but from the people I've been around who have been in this kind of situation, it pretty much takes a miracle to get them to leave or to be able to exit the situation safely.
I just wanted to add that as many here have already pointed out, domestic violence should always be taken seriously, even if all the facts are still being sorted out.
I went to Christian schools from kindergarten through high school, and was surrounded by the Word of God and all the things we "should and shouldn't do" every single day of my life. But somehow, it often seemed as if many of the Christians I knew never thought these issues would apply to them (because they were children of God), and often judged others who WERE dealing with such situations harshly.
My school was very small--at the time I graduated, we had only 124 students in the entire high school. But even out of that small number of students, two of the girls I knew who went on to "do the good Christian thing" by having "good Christian marriages"... wound up dead.
I've been following this thread since the start, but debated on whether I had anything to had. However, I want to mention these stories in order to point out that domestic violence is a pervasive problem that can happen to anyone, no matter what their beliefs are, what group they're a part of, or how closely they follow "the rules" or "do everything they are supposed to do."
I remember these two girls from school very well.
One was part of the "in" crowd--always at the top of everything there was to be achieved, extremely beautiful and popular. I remember her because she had hosted our freshman initiation, and all the boys had talked about how gorgeous she was.
When her husband shot (and kept shooting) her, it was one of their children who called 911, but it was too late. She was already dead, and all of their children had seen it happen.
The other girl had been the exact opposite in school--although also very pretty, she was quiet, shy, and part of the crowd no one wanted to associate with if they wanted to keep their popularity intact. But I was glad to see that she at least had a best friend she hung out with all the time, and I remember them both because they sat behind me in study hall. All this girl had talked about was wanting to get out of school and get married.
I was told that before the end, she had done everything they tell you to do in order to get away from an abuser, even going so far as to leave him and move to another location in secret.
But in time, he found her and hunted her down at her new apartment, and in his wrath at her for leaving him, he emptied a gun into her head.
Mania, I'm guessing that others have noticed/know about this couple's issues as well? Are there any older, more experienced members at church (those who have dealt with these things before) whom you could talk to about this? I would also recommend calling domestic violence hotlines (whether local or national) and asking for their advice.
I will most definitely keep your friend on my prayer list, and I sincerely hope that anyone else, male or female, who is in the same predicament will do whatever it takes to get away from their abuser as well. May God give you the strength to do what it takes to get out of this horrible, always-to-be-taken-seriously, and very dangerous situation.
