This series feels like an epic. I really want to know more. I like the twist in this, it works so well and you convey his feelings well, especially with the ’I’m sorry. I’m so sorry’
I think the first sentence could be split, the phrases are a little too long to only have commas.

I don’t disagree with your suggestion- at the time, I just wanted to write it before I forgot. I’ll sort that out.
