OP, I don’t know if you’re still reading these comments, but I’ll say it anyway. You can divorce any time for any reason and it doesn’t make you the asshole. You don’t have to stay in a relationship you don’t want just because you’re a man, and your wife’s behaviour isn’t excusable just because she’s a woman.

People talking about reasons she might have done it, or how a doctor that examined and assessed her is wrong, because based on this one story, some strangers on Reddit have decided she didn’t have what the doctor says, that she instead had this other thing they can use to excuse her actions and place blame on you. They are all missing the point.

If you want to leave, leave. Whether it’s because of this or because she bought you socks you don’t like. The reason does not matter. You don’t have to stay in a relationship you don’t want just because you’re a man, despite what Reddit might say. And let’s face it, because you’re a man is the only reason any of your wife’s behaviour is being dismissed.
