I can only speak as a parent 
I know that optimizing my son’s BG would not be possible if there were not two of us committed to it. And - I feel that, by analogy, for a PWD to manage it must be SO MUCH better to have the right partner!
@TiaG was writing earlier about how hard it must be for you guys going through it on your own, never having an hour or a day off – it really tears me up a bit every time I think of it for you all (and for my son too, of course, once he has flown the nest).
So when I read about @docslotnick’s, @Eric’s @Millz’ or @CatLady’s partners – or when I see how hard @TravelingOn works on her partner’s D, it is truly heartwarming – and sad to think of those who don’t have that kind of a partner.
