This isn’t about domestic violence at all. It’s about (and I’ve felt this way since I first heard the tune) a woman saying a typical (and 99% true) thing to her partner that he’s emotionally closed off. But he just takes the piss in return: “just like that murder in 63”, or whatever. It implies he has nothing to hide and isn’t even thinking of anything in particular when he goes silent. Most women are apt to assume blokes have some hugely deep thought going on if they’re quiet, but this isn’t the case at all, as men themselves will tell you! They’re remarkably simple creatures, and while they def have an inner life, they don’t volunteer their thoughts as a social connecting mechanism the way women do. No way he could have committed a robbery and a murder and she didn’t notice signs of a criminal or delinquent life when she started dating him.
I’ve had the same attitude from a new bf: one of our first mornings after I’d made us breakfast at mine and was then watching something on TV that I really enjoyed (probably a cartoon of some sort) he goes “K, I’m just trying to figure out what you’re thinking”. I was v taken aback as I’d NEVER been asked that by a man before. I just said “I’m just watching the TV!” I was genuinely surprised that he’d ask that question because it’s usually women who do that.

@meadowgroove PS: the gagged and bound phrase is, in my opinion, not to be taken literally. I think he means she wouldn’t stop quizzing him on what he was thinking. And the stabbing thing: equally so. I defy anyone to be in a LT relationship or marriage and NOT want to throttle the OP at some point. Or maybe every day.
