I married when I was 25, the reasons that lead me to it are not my proudest moment. I am not sure why you are discussing divorce, but it is a fact of life. Some people married and fall out of love and respect. And any justification is valid, it is their own. I divorced 13 months after. I was unhappy, he was too. We weren't talking for almost a year, no even Hello. So why would I share my life with someone who became a stranger?
If you are writing about divorce and you know nothing about it, try to do your research beyond the internet.
One of the advice that I give to young writers is always, write about what you know, what you have experienced so you can transmit the same feeling to your audience. If you have lived close to a divorce theme, and it was something rational for you, it is okay to describe it like that as well. You don't have to make every reader happy, you just need to torment them, make them question their own beliefs.
I hope this helps.
