Thank God he didn't have one of those "I didn't say anything because I didn't want to ruin everything for everybody else...' moments...
About 10 years ago, my neighbor, now deceased, had a stroke on 12/25. His family noticed but thought it was the 'flu' or something like that. One side of face drooped, one side of body wasn't working well, but they thought it was the flu? He had diabetes, high blood pressure and a host of other problems, most of which put him at high risk for heart attack and stroke.
Let's just say that 12/26 was one day too late to start treatment for his stroke.
Your husband did exactly the right thing, and so did you. Your priorities were in exactly the right place.
I will pray for your husbands continued recovery.
