In regard to your post @ 20:29 today, like many men I hate attending the Doctors. However, my wife and I have been married now for nearly fifty-one years and so know each others ways and normal personality very well.
In the above, if my wife noticed that I was not acting in my normal manner, by example being rather quiet or such, then I am sure she would soon be enquiring as to what the problem was.
If I told her it was some medical symptoms knowing my wife as I do, she would be telling me to "get over the Doctors" before the last words left my mouth.
In the above circumstances, I would attend the Doctors however much I would hate going, for that would be to save her the distress of worrying about me.
I believe the same would be in the vast majority of long-lasting marriages/partnerships, for it is the concern of one for the other that makes for a lasting relationship.
