I hope your father gets well soon Lost. I think the "right" thing to do is tell your husband. Your fathers condition could be serious. In situations like this, I feel its your responsibility to notify your husband. What type of relationship did they have?
I know it's tempting to not tell your husband. If they had a cordial relationship and it ends badly, your husband and your father maybe robbed of their last opportunity to speak with each other. It is not right to prevent that from occurring. If your husband does nothing with the information, that's on him, you've done the right thing.
By punishing you husband you maybe hurting your father. Why would you want to cheat you father of closure?
I believe we don't have the right to keep that kind of information from people. That's my opinion and probably not a popular one but I think it's the compassionate, kind, loving way.
