A wonderful story. Yes, I got teary in parts. It could be a book a reader won't put down.

The plot is good. I think you could develop this story into a longer novel, show a bit more about the boy's lives as well as more about their adult lives. I'd like to know more about Jake, his family.
Your writing style is similar to what mine was when i first started writing. As you write more your work will improve. I think you need more dialogue. I'll admit to bad grammar...
Technical skills. You need to brush up on these...in this story. You have mixed tenses, first-person and third-person mixed, In some dialogue, you have backward speech marks at the end of a sentence and an extra comma. You also need to use more contractions in your dialogue. This will make your story flow much better. Last but not least...watch out for word errors or extra words which can be removed.

Meanwhile, please keep writing. You most certainly have talent.
