I have been rather critical of H&M since their "Half in half out" statement, but right now I feel rather worried about them.
I think it's been the perfect storm of things happening to a couple who (it now seems) are far more vulnerable than they initially appeared.
Despite M's previous experience with being an actress, she doesn't seem robust enough to cope with being on public display, as being a working member of the royal family demands.
This is not a criticism, it would have had me crying in a very short space of time.
They got engaged and married very quickly, having mostly lived on different continents. M did not have the time to get used to the press intrusion and decide whether the life of a working royal was for her.
I don't think they really knew each other that well either, having barely lived together before they were engaged.
H had met Doria but not Thomas Markle. This is a rather large oversight given her clear affection for her father (see her father's day post in 2016), even for someone outside the royal family.
Within the royal family, it was a huge mistake for both H and the royal family not to have looked after M's immediate family and helped them to navigate the media attention.
Then they threw themselves into being working royals. From the OW interview, H makes it clear that there were more than a few suggestions that M did not become a working royal, so it's clear that they were not pressured into making her one.
Rather than just going off and having some time to themselves (to actually get to know each other properly) they thrust themselves into the limelight.
They both cope very badly with any negative commentary in the press. It's clear from the OW interview that H&M are much more aware of the press articles than they like to admit to. They do not like the "never complain, never explain" mantra, and want every negative article corrected.
M found the confines of royal life a strain (I would too). She wanted to be able to have her own opinions and not be told what to do or what to say.
That is fine in theory, but the royal family pay heavily for talented PR people whose job it is to maintain very good impressions of the royal family.
H&M might not like being told that certain topics should not be discussed, or having speeches heavily edited, but if you look at the image of H before his marriage and his image now, I think the PR people were probably well worth their salaries.
They decided being a working royal was not for them (which is completely fine, and probably a wise decision) but announced it before working through the details.
So they have been left having to pick up a hefty security bill, and having taken on a huge and expensive house, with staff, without a sufficient guaranteed income to cover it.
They don't appear to be listening to the PR firm, and H in particular appears to be unravelling on camera for the world to see.
The fact that H&M seemed unable to reach out to M's Obstetrician, a GP, or Harry's own therapist, when M was suicidal, makes it look as though H was already struggling to cope.
H had many avenues to get M some mental health treatment, and he did not do so. M was suicidal, so it's understandable that she did not know where to start, but he was seeing a therapist at least once a week. He could easily have mentioned it.
It feels like they are being exploited by those around them, and it doesn't appear to be doing either of them any good.
