Whether she has a small apartment is really her issue. I assume she left the marriage? If so, she's made her bed and it's not up to you to accommodate her and make moving on easy.
IIMHO you need to take back control of your life because at the moment it seems like you she has you eating out of her hands because you are looking for any breadcrumbs that she might be offering.
Sorry, I don't mean to be harsh but you've got the right to a life as well but at the moment it all seems to be about what she wants and what she can get out of you to enable it.
