I went to another session of my DivorceCare support group last evening. This session was on Finances. One of the things they focused on was how a divorce seriously alters the lifestyle of both people because of the changes in finances. Suddenly two households have to be maintained on the same income. It is not something spouses should take lightly, and is one reason why their first recommendation as a solution is to "Abort the Divorce", if at all possible. But of course, they went on to provide further contingencies, since so many these failing M's still lead to D.
In your case, the one thing they brought out is that now of days, with so many D's taking place and there being so many SAHM's reentering the workplace, many employers are starting to take that into consideration. Some even offer employee training assistance for women in this situation. (This was something I never realized until I heard it myself last night.)
