I'm very aware that one of the benefits of posting on a forum such as this is that you can gain clarity from anon posters offering dispassionate advice.
Equally, there are invariably nuances to a situation that can mean that advice isn't always the optimal way forward at that point in time.
So no, you've no need to think anyone is disappointed by your decision and I'd hate to think you'd stop posting and getting support for that reason.
It's your life and the consequences are going to be yours to own long after this thread is archived though age.
That said, I stand by my posts, specifically that when I said to be mindful of his response when you spoke to him.
Specially that his response will not be based on what he feels or what is best for you and he children, rather a response designed to facilitate the outcome he desires based on his own self interest.
Based on everything you've said I have no hesitation in concluding your H has exhibited abusive behaviour towards you for a long time.
You therefore need to understand that your perception of his behaviour and motivation has been filtered through that lens of abuse for a long time and may well be distorted.
I talked in an earlier post about balance scales.
Consider that now he knows the sulks (and the super charming flip side) have no "weight" that he's simply offering up an alternative strategy - to the same ends.
"Mr I'll go to Therapy" and "Mr I'm in Pain/coming to terms with diagnosis" still all tip the scales in his favour. It's still all about him and "excuses" designed to put you on the back foot.
Please be aware of that and I would reiterate as a PP has already said that joint counselling is a very bad idea for you in these circumstances.
It could well be that your stance has prompted a sense of self evaluation from him but you'd be unwise to take that on faith presently (and for some time).
I'd suggest you keep a diary to enable you to reflect on his actions/your feelings (it could simply be this thread - as I said there's no judgment, only support and concern for you - or maybe a secure online journal) so you can read back, reflect and spot patterns of behaviour that you're now much more aware of.
