I don't know... M&H to put it politely can be... quite irritating in their public pronouncements? They certainly know how to push people's buttons anyway!
However I don't think that stops it from all being quite sad. It's impossible to know what goes on behind closed doors however a lot of what they have said about public things just aren't true.
For example, all those years ago the "intro" British people had to Meghan Markle was Harry publishing a statement asking the evil British press to leave her alone and stop being racist - but at that point, nothing had been published about her, and nobody knew who she was. Similarly when they talk about what horrible coverage she got leading up to the wedding - that just wasn't true, 99% were really excited, supportive, most felt very sorry for Meghan about her father standing her up, etc.
I don't know... it's very sad, I know they both have/had mental health issues, it's really sad that they never realised how well-liked they were, and now because they THOUGHT they were hated they behaved in a way which means that came true and now a lot of people really don't like them.
I don't think mental health is an excuse to treat people as badly as they did, but nevertheless I do feel sympathy for M&H. Their family will probably never really forgive them - I don't think I could forgive someone if they did even 1/10th of that to me!
