She probably told him she wanted a divorce. He probably has been physically or mentally abusive for years. Oftentimes men when kill their spouses and/or children rather than let them leave. In fact, it is extremely dangerous to leave an abusive spouse, NECESSARY, but dangerous. The beatings or threats turn to murder rather than letting the spouse have her freedom or take the kids away from him.
We live in fear that my ex-son-in-law will do the same thing. He is a vengeful, insane monster and we won't be able to rest easy until he is dead and gone. We just pray he doesn't take anyone with him.
1. Abusive spouses CAN control themselves. They don't beat up their boss, their neighbors, the local cop or the local minnister....they beat up NO one except the fool who allows herself to be beaten.
Please don't start the lecture about abused women syndrome. Men who beat women seek out women who will allow themselves to be beaten. It NEVER starts the day after the wedding. That kind of nastiness starts WAY before....unless a woman is foolish enough to marry a man before she knows him well.
Then, she claims that she is stuck. Sure she is because she allows herself to be. Adults are NOT weak, helpless, innocents who are incapable of changing, moving, growing and being responsible. They really aren't.
2. As for your vengeful, insane ex-son-in-law, one wonders at your daughter for ever marrying him. I hope she didn't stay long enough to have children with him.
3. You live in fear? That's sad. That's no way to live. You two should pray to God for courage. (I do every day, just to stay strong.) As Johann Wolfgang von Goethe wrote:
Wealth lost, something lost; honor lost, much lost; courage lost, all lost.
