They’re divorced for different reasons. It’s complicated but they have they’re own issues that didn’t work when together. My dad being emotionally unavailable and my mom being in a vulnerable and emotional state that was taken advantage of and didn’t get any emotional support which led to her being emotionally unstable. The marriage was already failing but when my dad also got another woman pregnant that ultimately led to the divorce being finalized. He did not tell any of us she was pregnant until she was already 5 months so it was very shocking and upsetting for everyone.
