My advice remains the same. Yes, the part about children's homes doesn't apply, but instead of that (if he is not employed) he gets to fight the benefits system, which is even less in his favour.
Nowadays it takes 2 appeals to get anything at all in the way of financial support, just because it's easier on the government to refuse help in the first instance. This is especially the case with mental health and neurological conditions. I'm lucky enough to be able to work, but I have friends who have gone through it and it is hell.
If he IS employed, you only have to look at this forum to find how hard many autistic people have to fight to stay in their jobs and get the support they need therein.
And honestly, whatever his age, you say your son is sometimes suicidal; I fear losing the emotional support of his mum would just tip him over that edge. He absolutely does need you.
