Not exactly the answer you asked for but my mother’s parents were the only grandparents I knew (dad’s parents died before I was born). The got married in the early 50s and got divorced in the late 70s or early 80s. From my understanding, they were no longer in love and they knew they couldn’t stay together but after the divorce they remained close and involved in my moms life and later were both very involved in my upbringing. My grandmama died when I was 5 and my granddaddy died when I was 18. My mom’s parents will always be the most special people in my life, aside from my husband. When i was in my teens, my mom gave me their wedding photos and those will always be one of my most beloved possessions. I know this doesn’t fit for every situation, and if the person you divorced was a shit person, light those photos on fire. But if you marriage ended even remotely amicably, please hold on to those photos for later generations to see.
