Update: I told my wife that my life would be better without her. She went nuclear, so I responded in kind.
Two weeks ago, I had an argument with my wife, Anne. This argument stemmed from Anne's incessant need to contradict me and everything I say. Anne left in a fit of rage to stay with her parents, and then kept spamming me with texts demanding an apology. A few days after Anne left, I felt something I hadn't in a long time at home: peace. I didn't have someone nagging me about literally everything I did. I didn't have to eat my meals in the "correct" order (something about pH balance that she probably saw from some brainrot creator on TikTok). I didn't have to wash my feet after getting home. I could actually enjoy myself, which is impossible when Anne is around because I found many years ago that she tends to get the most aggressive when I seem like I'm either in a very good or very bad mood. I then did something I never thought I'd do: I reached out to her ex. He was more than eager to talk about Anne and her shenanigans, so we met up for drinks. He and I both had near-identical experiences with her. Anne is, through and through, a pretty horrible person, especially to her romantic partners. He cited irreconcilable differences for divorcing her, where it was no specific event, but just a long list of terrible interactions and coming to the realization that he detested her as a person. During this time, Anne went silent on me. I used this lull in our relationship to visit a lawyer, who told me that due to the nature of laws in our state and the fact that Anne is able-bodied and educated, the chances of me ever having to pay alimony are basically zero. I called Anne at that point. She, for some reason, still expected an apology. I told her that I wanted a divorce. She threatened to "take everything" from me. I said she could try, but any further contact should be done through my lawyer. I'm fully happy to split our assets fairly. I'm fairly sure that Anne will agree to any deal that gives her more than half (it's just the way she is), and if it's a 55/45 split, I don't care. All I'll have to do is act like she got the better of me, and since she's an idiot, she'll happily agree. Thanks to everyone who responded in the last post with advice. Tons of you suggested divorce, which I think was what actually got me to consider it seriously.
