Well, you probably already know you shouldn't have moved out, so I won't belabor that point.
However, you need to find a point of consistency - are you going to sign the divorce or not? Your WAS is following a pretty consistent path - find some OM that "needs" her, because he has no job, clearly mental issues, etc. I can tell you from experience that delusional state for your W can last for months, maybe more than a year, and on and on, who knows how long.
The real question here is - how are you making yourself better? "Winning her back" is completely wasted effort because you CAN'T do that. The only thing you can do is be the best person you can be - and perhaps, that's enough for her to want to be the best person she can be, and heal your marriage.
So your only focus should be on being the best you. Period.
