Gunny For many WAW's there's a series of milestones they must complete in order to move on. For each one they complete it becomes a little harder to turn back. Depending on the WAW's some milestones are easy, some are hard.
Some good examples are moving out, getting an apartment lease, and in your case getting a job.
What makes them hard is that each milestone further solidifies the separation and divorce. The WAW has to think hard about crossing each milestone, because it'll probably feel like after they cross there is no looking back.
I know you worry about your W landing a job, and that being the end. I can tell you from personal experience that it is not. When she does she'll have to stop and think about the ramifications of her taking the job. As she keeps going the separation becomes more and more permanent, give her a chance to see if this is what she wants.
