I did not but your question is confusing. Do you want to stay? I stayed with my EH until I found a place I thought was appropriate for me and DD to move to. It was about 5 months after we decided to divorce and 2 months after I filed. We even slept in the same bed. Our divorce was very amicable though.
I don't see the relation between short sale and staying.
Our split was amicable. We stayed together for about 2 months while I saved cash, then I found a new place. It was my choice cause I wanted to keep our dogs and so I found a rental home with a large fenced yard for them. We are still going through the short sale process, and until it sells, XH transfers me money each month equal to half of our previous mortgage payment. It's just an unofficial agreement between us because we decided it wouldn't be fair for one of us to be paying full rent and the other nothing. Obviously this would only work in the case of a very amicable split. In reality there is nothing protecting me and he could stop paying me any time he felt like it. I am renting a place that I can easily afford without help from him though just in case. Hope this helps!
