Firstly, thank you for sharing! I enjoyed getting to know you two as characters in a story.
With that said, as someone currently living in a city where a 12–15 year age gap is seen as absolutely NBD, I found it peculiar to see so much value assigned to a mere difference of age. I mean, you said it yourself — he feels older and wiser than you in many ways. The truth is, age has such a looser bearing on the depth and developed-ness of so many other important qualities that, in a lot of cases, it begins not to matter.
We gotta stop giving so much damn power to silly wrinkles in controlling our lives ;) you look beautiful!
