It is very important for you to build up a savings or emergency fund that will get you through the tough times that may be ahead. If you are not in the work force, consider updating a resume, and perhaps even applying for jobs, so that you do have some safety net. If you will be keeping your house, you may consider taking on a housemate to help defray the costs of living alone. You may also want to establish your own credit cards separately from your soon-to-be ex-spouse.
