I feel for you, as I'm having some similar issues. My wife bought a house in Dec, but she's still here. She's "fixing up" the other house, but "don't worry, I'm definitively moving out". And I'm paying for it all.
On the one hand, I suspect I have a better chance to reconcile if she's still here, but on the other, I am sure she's leaving, so I wish she would get on with it.
For what it's worth, when the couple across the street divorced, they sold the house, because, in her words, "he just wouldn't leave." A bit extreme, but that's what it might take.
