My brother went through a divorce last year & IMO moved onto another relationship far too quickly. I have no problem with his new girl, I just think they moved things along at far too quick a pace and now have to sort things out better. IMO, if you see other people - just see them. Don't move into together or make other much more firm relationship arrangements right away, as even if you don't think so you're going to need time to sort yourself and your life out post breakup. FYI he's AS (but doesn't accept it yet) & his ex (afaik) NT, and afaik the new one (old flame from high school days) is NT as well. If I were in your shoes, I'd enjoy my solitude for a bit - even if dating - and take a good year+ of living solo to really figure myself out and what I want/need out of life and a future relationship before diving headlong into one. No, there are absolutely no set rules on timeframes, and everyone is different, but I just don't think jumping right back into co-habitating is a very wise move.
As for the future ex, that's a tough one. I have NT friends that would say it's not their problem where she lives or how she pays her bills, just get her out of your life and move on. But that's cold. If she's capable of working, perhaps she could use the time you still have living together to find a job? If she isn't, maybe this will spark her into getting help for her depression if she hasn't sought it out over the last 6 years. As for finances, whether her or you, it may make sense to look into what her options are for some sort of social assistance in order to get a place of her own if she can't work.
