Just sharing thoughts in case others can relate. My parents divorced nearly 20 years ago while I was a student but I just got caught off guard listening to a Beatles song. There was a lot of 60s music in my childhood home.
Being an adult it wasn't traumatic, I already had a life away from home - in a different country and have never moved back. Married now with my own kids.
I still have the odd little moment of wishing it had been different. Maybe its just the same pang of nostalgia for childhood that any adult might have?
