I do agree about the comment on the 10-20% part though is that they feel they are in some way settling, giving up, or whatever they may feel by staying. I don't want her to feel that way at all.
You don't want to be with someone who doesn't want to be with you. If you value yourself you wouldn't want that anyway.
Set them free, let them make their own choices. You want them to return because of the love they have for you not because they didn't want to get a job, or because they couldn't make it on their own or because they didn't get to live the same lifestyle.
If you allow this to happen you will continue to be in an unsatisfying MR and you will be miserable.
Work on getting stronger in all aspects of your life (spiritually, physically, emotionally) and if you do your W returning won't be as important as it once was.
When I first joined the board I literally spent hours a day reading through sitch after sitch trying to learn as much as I could. I came across this quote from like 10 years ago that really stuck with me.
"Those that work the hardest to save their MR have the least success"
