Divorce comes down to numbers, no more or less. Contacting several competent lawyers to understand your legal rights and typical outcome is a basic step to take when your spouse is intractable. This is educating yourself on a potential action of this situation.
It doesn't matter if the economy is tanking or thriving when a spouse leaves. It doesn't matter if you promise her the moon in hopes of keeping her there.
When someone is hellbent on breaking up the family, their feelings are based solely on themselves, not on what's in best your best interest as a couple, the children or you as an individual.
Decide what is fair and equitable with firm legal advice. Decide what works for you, not her. And remember you will have your own household, costs which reflect your needs and those of your children.
This is not saying to pursue divorce. It's putting your ducks in a row and knowing how to protect yourself if the event happens.
