Keep in mind that while you are in the process of divorce, the divorce itself is costly and you'll need to keep that in mind as you budget.
If you do end up divorcing, things will be tight for a while, but you'll eventually get the hang of reducing some of your day-to-day expenses, i.e., coupon clipping, watching for deals at the stores, etc. It's best to begin tightening the belt now so that you can get some money stashed away.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
