You didn't know then what you know now. A lot of people say of past mistakes, "I should have known." But that's a crock. You DIDN'T know. You were brought up all your life to cherish women.
Here's an extreme example. Back when I was 13, my family visited my great aunt in Austria. We had just had a huge meal on the plane and were all groggy and full. Then when my great aunt met us, she thought we must be hungry after a long flight, so she brought us to a restaurant and ordered a huge meal for us. None of us spoke German, and she didn't speak English, and we were unable to make her understand how stuffed full of food we already were.
Today I speak fluent German. If I went back with today's knowledge, I could just explain to her in German that we had already eaten. How stupid would it be for me to say, "I should have known German, and then I should have just explained it to her"? I DIDN'T know German.
And way back when, you didn't know not to simp. That was what all of us were taught to do, and it was supposed to work. Some beautiful woman who was sick and tired of the Chads using her and not appreciating her were supposed to be impressed by meeting a man who respects and values women.
You didn't know back then. You had no clue that respecting and valuing women had the exact OPPOSITE effect that you thought it should. You thought she would think, "Oh, cool, I'm sick and tired of these cads who just use me. Here's a great, respectful man. I'd better grab him." You kept thinking that would happen, but it never did.
You had been fed a bullshit script. There's no sense thinking back to the dumb things you did following the crappy script. You know better now, and so life can be better now. You can't go back in time and do things better. Therefore, there's no sense worrying about the past that you cannot change.
