Bah. My wife has thrown things at me when I've gotten her REALLY fired up, but it only happened in the first two years of our now twenty-year marriage. Admittedly, I knew I should have stopped turning her knobs so much each time it happened.
Nobody here except the OP knows exactly what happened, and the OP doesn't seem very concerned. Lots of jokes are going around. Nobody needs to call the cops. Let's be adults here, and realize that sometimes things get heated between married couples and don't need to be labeled "domestic assault" every time something gets broken.
I'm not trivializing abuse, because I realize how serious it can be, but I've seen this get completely overblown with a close friend. His wife was on the phone with her mother while she was arguing with him, so her mom called the police. Nobody got hurt - the argument didn't even get phyical, her mom didn't like the way he was banging on the door - but the cops hauled him away to spend the night in jail. They ended up spending thousands of dollars on fines and classes, and the original argument was based on money trouble to begin with. The incident also prevented him from entering the career that he was going to start after graduating in a couple of months. They still haven't completely recovered financially from that night.
I kinda agree about the "her problem" part, though.
