One of the most difficult things about divorce and separation is the uncertainty and confusion people feel. Mediation can help you work out what your options are.
Sometimes, none of the options will be especially good from your point of view, and that can be difficult and unhappy.
However, once you know your real choices, you can start to regain control of your life and decide on the choice that seems to both of you to be the best one for your family overall.
Making things better is a good goal.
