To me this is completely okay and a heartwarming success story.
Sure there is the alternate history where you stayed in touch and he still remembers you and cherishes the relationship…
But it’s also wonderful that he impacted you so strongly and positively, yet has taught so many students that he doesn’t remember you specifically. If he did this for you he likely did it for other students too and we are lucky that we have him as a teacher in our world.
It also reminds us that though we know ourselves to be human with very human limits, we can still pay forward the kindness and guidance we received to the next generation.
