I love the end of this paragraph:

I know you will assure me that I am foolish and that you want me to have full happiness and don’t want to be in my way. I’ll bet you are surprised that I don’t even have a girlfriend (except you, sweetheart) after two years. But you can’t help it, darling, nor can I — I don’t understand it, for I have met many girls and very nice ones and I don’t want to remain alone — but in two or three meetings they all seem ashes. You only are left to me. You are real.

It must be hard to be a realist but love her so much. His logical mind would refuse to believe in an afterlife or any way to connect with her but his emotional mind would have been weeping.

Do I have anything to say about this? Well, you can take from it what you will. I’ll let the letter speak for itself.
