RHOBH Yolanda and David divorcing?

Just saw a blip that said they had announced they were getting a divorce... We see the shows a week or more later up here in Canada so I try to avoid reading/googling for info until I've caught episodes...

I know she's been ill, he works a lot... Guess I'm nosey if it there's more to it, or if it's as simple as it wasn't working any more...
