Not quite the same gap but I grew to be good friends with a work buddy in his 40s when I was 25.
Throughout my life I tended to connect better with people older than me.
But if you have bad vibes beyond just the age then it may be worth talking candidly with your son about your concerns.
I've had friends 20 or 30 years older for well over a decade.
... your son is an adult. I think you're being the weird ones about this personally.
