Throwaway for obvious reasons. TL;DR at the bottom.
So, background: I (51M) come from a *very* influential family. Like, my dad could buy your dad's company and turn it into a parking lot for funsies. When I was younger (20s), I fell for this girl (now my wife, 54F), let's call her Anon. She was literally perfect, an SSR-tier waifu in a world of N-rank normies. Problem was, she was a poor. Nothing wrong with that, but I knew she deserved a better life. A life only oppa could provide.
So, I devised a plan. I needed to show her how dark the world could be so she could appreciate the light I would bring into her life. Character development, basically. I used family connections to... let's say, 'encourage' a series of financial misfortunes for her. Some scams, some sabotaged job interviews. Basic stuff. This led her to being desperate enough to participate in a... high-stakes, high-reward private event my family runs. Think of it as an extreme team-building exercise. I joined as a masked staff member (manager-rank, obviously) to watch over her and make sure she was safe. Think of me as her guardian angel. Her secret oppa.
Long story short, she won (with some of my behind-the-scenes help, she's amazing but a little clumsy) and got a huge cash prize. A few months later, I arranged a "fated meeting" at a café. I was my usual charming self, and she fell for me hard. She never connected me to her 'guardian angel,' but I think on a soul level, she knew.
Fast forward 30 years. We're happily married, have a son (28M), and a beautiful granddaughter. Our life is perfect. My wife has never had to worry about a single thing. She is happy, loved, and safe. My life's mission has been a complete success.
Here's where I might be the asshole. My son found my... 'Personal Log™' from back then. It was a private journal on an old phone where I documented my plan and my feelings. Lots of detailed notes about how breedable my wife looked in her uniform, my fantasies about saviorfagging, some cringe rants about the middle-management trying to cockblock me. He's flipping his shit. He's calling me a "monster" and a "manipulator" and says our whole family is built on a lie. He threatened to tell my wife everything.
I told him that her happiness is all that matters, and the methods were justified by the result. He thinks I'm a psycho. I think he's a naive zoomer who doesn't understand that true love requires sacrifice and extreme measures.
AITA for building a perfect life for my wife on a foundation of, let's call it, 'coercive romance'?
TL;DR: I financially ruined my now-wife so she would have to enter a death game where I secretly protected her, then introduced myself and married her. We've been happy for 30 years but my son found my "Stalker Diary" and wants to blow up our perfect life by telling her the truth. AITA for defending my actions?
