This is a bit off the beaten path for this blog, but Hilzoy's post on the psychology of spousal abuse should be read, and linked, by everyone. It's one of the best blog posts I've ever read. An excerpt:
To start with, it helps to know that (last time I checked) the two most common times for violence to start were the honeymoon and the first pregnancy. By the time you reach either point, you're already in a pretty serious relationship, and leaving is not something that anyone would do lightly.Moreover, the violence often comes as a real surprise. It's not that there aren't signs: there are. But they are often things like: he falls for you too hard and too fast, or: he wants to be with you all the time. You'd have to be either paranoid or a victim of a previous abusive relationship to leap to the conclusion that either of these things means that abuse might be in your future. (Imagine, in particular, someone whose last relationship was with someone who didn't seem to care about her: imagine her saying to herself: last time he didn't care enough; this time he seems to care too much; am I impossible to please?) So imagine yourself, in love with someone, on your honeymoon or pregnant, when suddenly this guy just goes ballistic, often for very little reason, and hits you. For a lot of women, this is profoundly shocking and disorienting. There are things that are comprehensible parts of the world, even if they're rare, like having your car stolen; and then there are things that are unexpected in a completely different sense, like having your car turn into an elephant before your eyes: things that make you wonder whether you're completely crazy. Being beaten up by someone who apparently loves you is one of those things. What this means is that precisely when a woman needs as much confidence in her own judgment as she can muster, the rug is completely pulled out from under her. And it's not just that she questions her judgment because she got involved with this guy in the first place; she questions her judgment because something so completely alien to the world she thinks she knows has just happened.
