My DF has cancer, given 12 months last June. He's really not well now. My family is totally hopeless at talking to each other but I feel like I need to tell him how special he is, how much I love him, how grateful I am for everything he's done for me. I couldn't say it to him without collapsing in tears. Is it ridiculous for me to write him a letter? Do I assume he knows all that instinctively? I think I will regret it if I let him go without saying them, but it feels a bit like a premature goodbye.
