In this type of circumstance, it is best to get legal advice so you understand your legal rights & options.
If she leaves with the children, she must tell you where she will be living. If you feel that she is behaving unreasonably, you can file an 'ex parte' (emergency) order to address child custody, visitation and support.
Normally, in this type of situation, you would file for divorce and then file a Request for Order to address child custody, visitation and support as well as spousal support.
