Is it time to walk away from my marriage due to my husbands poor mental health?

[Jollycolours]

For the last 10 years it has come to light my husband has been keeping a dark secret from his childhood that has made a huge impact to his mental health. Severe anxiety, social skills, mood swings, and depression. Although been on medication for a couple of years, he recently decided to stop taking his meds. He shows no emotion, can't speak to anyone and says he won't speak to anyone... because he can't.
He wants us to split up because he realises how hard things have been for me and the kids.
Sadly, I don't want this, I understand why he's saying that, but I don't know why he would give up on everything, and not want to help himself, or us! I can't make him take his tablets, and I can't make him speak to someone.
I'm incredibly sad, because I don't want to walk away from him.

Let him know there are types of therapy that don't require deep soul searching, or even anything more than very basic information (and they work - because he knows the details and that's all that's necessary). Would he be able to engage with that?

He is adament he won't speak to someone, he just can't see that anyone will help him sadly

That's sad. These two videos might help him realise he's not alone;
