Hi Ganb8te. I'm not sure how I feel about you giving over the letter, as it *generally* seems like a method of pursuit. However, in terms of how the letter reads, it is very calm and well articulated and to-the-point.
The only issue I have is that it seems, overall, that it is a question. It reads to me like it needs an answer. And I'm not sure he's ready to give you an answer.
I think you should continue to explore methods of communication with him and hanging out with him and being your best self, but I think you should try to avoid any R talk at this point.
