I feel I really need to add one thing to this thread, from my perspective, as I seem to be the one who voiced what others appear to have agreed with, and somehow enabled their comments.
Personally, I would disagree with
@Molly56 when she says I criticise. I would say I have given feedback, which is what she asked for way, way back. That feedback is based upon a number of days, weeks and months of observation of serial updates with little material change in either actions or outcomes.
That Molly chooses to disagree with the feedback is absolutely fine, and if Molly is committed to supporting and standing by her man, whatever happens, that's also fine, but that's not what Molly has "verbalised" along the way. Molly has stated she is distancing herself and withdrawing day-to-day support, in terms of repeatedly encouraging a testing and dietary regime, but not actually having what I feel are the important discussions with the only person with whom those discussions should be taking place; her husband.
In my view (which is unchanged), unless Molly and her husband do not have a full and frank discussion, where each party discusses how they really feel about matters, this mis-match of expectations, and outcomes will plod on to a probably predictable outcome. I find that incredibly sad. And again,
@Molly56, I would ask you to reconsider this position.
Once you both properly understand the real feelings of the other, then you can probably formulate a way forward, which will involve support or one of you walking.
If that feels critical, then I suggest you re-read the thread, from the beginning, and perhaps make notes of your statements along the way.
I think you are in a rotten place Molly, but, I reiterate, you are in control of how it moves forward. Your actions have as many consequences as his.
All actions have consequences. Inactions have consequences too.
