I've disclosed for 41 years. Lost my husband close to 4 years ago whom I also disclosed to many years ago (over 30). Once I disclose, I feel I've done my part. I do, obviously, do my part to keep them safe, however, if anyone was to aquire it, I'd feel 100% that I did all the right things and everything I could to avoid passing it on and would not beat myself up over them acquiring it.
