Big regret in my life

I made a big mistake in my life. Everything was going well my career, my life but I ended up marrying the wrong person, and now we are getting divorced within a yearacter marriage. We met seven months before the marriage. During that time, my father passed away and our house construction was happening, so I was mentally overwhelmed. I put all my effort into the relationship, but she didn’t show much interest. Even before the marriage, I felt something was wrong, but I still went ahead because I didn’t want to worry my family who were already grieving. Now I feel sad because deep down I knew this could end in divorce, yet I went ahead. I don’t know why I did it, and it feels like everything was going well in my life until I collapsed it myself.
