I think it is good that he is realizing he can't keep up what he is doing. Whether it improves things with you or not.

Now, I think this:

I suggested possible scenarios that would allow him to keep both jobs but for example work as an advisor to the morning one, going once or twice a week at the office and he said he will think about it.

might have been a mistake. For one thing, I don't think he wants you to try to fix his problems. The other thing is that "advisor" jobs have a way of sucking you back in, and you end up right where you were before.

I think it is ok that he is thinking of it as a survival thing right now, as worn out as he is he probably can't think about how it might change things with you. Let that happen if it happens! For now, just support him if he decides to try to change things. I think that changing his life might be the first step in changing you life together.
