If you move and the other party does not file in Tennessee for six months, your plan might work. The problem is if you move without an agreement to Florida, and they go to a Court in TN and ask for an Order requring you to bring the children back to TN, they will probably get it. You might run into other problems as well.
If the last place you all live together as a married couple is TN, this is likely the correct state for a divorce.
