Until a court has entered orders regarding parenting time (i.e., prior to a divorce), each parent has an equal right to parenting time and she could relocate with the kids. To stop this, you need to file for divorce (you could file for just allocation of parental responsibilities as well).
Once your spouse is served with the petition for dissolution of marriage, an automatic injunction goes into effect barring either party from leaving the state with the kids and this injunction can also be used to keep her from moving the kids across the state to maintain the status quo and to not "disturb your peace." Please let me know if I can be of further assistance. I hope this helps.
