I am so proud of your son, that despite going through all this you raised a proud man who is every bit as good as the old block. I can't truly relate (yet) as my son is just hitting 2 in January, but I can't wait to experience his accomplishments and triumphs as he grows up whether I get to do so with his mother or not. It's a triumph to know that no matter what, as a man we kept our eye on the prize to make our children better people than we could be and as your son goes off to do his duty, I can't help but salute you on a job well done (and yes, I am aware the job isn't entirely finished.)
