How does she believe she is just going to jump out into the workforce and be able to do this with all the issues she is dealing with?
Unfortunately that is her situation to figure out but I would say this. Assume you are D what would change financially for the both of you? What would you have to do to make it happen financially? What would you have to sell?
When my W told me she wanted to move out we both had to make financial sacrifices to make it happen. For example, we had a $900 a month car payment on one of our vehicles. I sold it and got something cheaper for $650/mth. I was putting in roughly 15% each paycheck into my 401k. I had to reduce that to zero.
My point is that if you get a D then you will be forced to make it happen. My philosophy when my W approached me to move out was to set her free and if you want to go let's sit down and find out how we can make that happen. I wasn't going to hang finances over her head.
I am not advocating that you push her in either direction but if your D was going to be final tomorrow so how you would figure out a way to make it work.
