I married her for a year and we got divorced so married her cousin to whom she was engaged before me. He divorced her 9 months later. After that once again we got married and the problem is after 32 years I regret what I called my life's mistake. I'm right or I'm not? please help with your answer thank you.
You must forget the past and live in the present. Whether it was mistake or not doesn't matter after that long time span of 32 years.
You've made certain decisions in the past that affect you today, but you probably thought before you took a certain path in life, right? Therefore in the past it was probably the best decision, since you weren't able to look into the future.
So yeah, regret until you turn blue if you want to, but your decisions were not a mistake!
Plus, after so many years, why bother thinking about it anyway? Life's ahead, you're still young, focus on the present.
My 2 cents.
32 years is more than enough time to forgive yourself. Enjoy your present, that's what you have.
