Never believe the threats of your spouse.
They are designed to frighten you into accepting less of a financial settlement and otherwise make you fearful of going to Court. (As a matter of fact, the vast majority of divorce actions are settles, many on the day of trial, through conference with the Presiding Judge.)
Some threats range from leaving the state to preventing visitation with children. Most are idle. Some are real. All of them have been tried before. The law has provisions for all of them.
