It's just that I'm mentally years beyond him in maturing, so in his mind that automatically makes me a grandpa
It sounds like you're dealing with a significant gap in maturity levels. While you see your advanced emotional and intellectual development as a strength, he might perceive it as a generational divide, humorously labeling you as a "grandpa." This isn't uncommon when one person in a relationship or friendship progresses at a different pace. The key is to appreciate these differences and perhaps use them as a basis for growth and understanding rather than letting them become a source of friction.
