Well, DB says to expect nothing, so perhaps it would be best to move on as if you were on your own. Let him take the lead in the conversation, maybe ask if he's been looking around at apartments. I think if you give him a reason to think that you want to move in together, he might panic and run. Avoid "we" talk. Like, don't say, "Where should we start looking?"
For my own H, we have been seperated for 6 weeks, and we divided our finances a month ago. He still hasn't done any paperwork AT ALL for divorce, we haven't met with a mediator or anything. So just because you seperate finances, that doeasn't necessarily mean divorce is next on the agenda. If anything, it helps because it makes him more accountable for himself and gives you less reason to contact him, so it helps you "go dark" more.
Have you thought about possibly renting out your house? You would have the income, plus it gives you the option of moving back in if and when your H decides to come back.
