I do not think that he can. Did you make sure to get his approval in writing? It sounds like you may have email confirmation which is likely good enough; particularly because you don't need permission (typically) for a move less than 50 miles. I would review your Final Judgment very carefully, if you have not already. You can't control what he does or what he files.
Please be advised that any answers or information disseminated above do not constitute legal advice and that the attorney responsible for this posting is merely attempting to participate in a Q & A session intended to be helpful but certainly not intended to be legal advice. It is important that you understand that no attorney-client relationship has been formed and that the attorney has no obligation to follow up with you with your legal issue unless you separately contact said attorney and arrange for him to legally represent you.
So you appear to know about the relocation statute in Florida. That is a good start. The 50 miles is 50 miles from where you resided at the time of the final judgment, so his moving is not relevant. Keep the email and the full string of the email conversation, just in case you need it at some point. He would have to file some kind of motion to ask the court to review if you violated any part of your final judgment/parenting plan. If he does file a motion and you receive a copy of it... contact an attorney who practices family law in your area.
Best of everything to you.
He cannot successful have you held in contempt because he now moves in order to make the distance greater between the two households.
The statute looks at the location at the time of the entry of the Final Judgment.
Nothing in this post should be considered as specific legal advice, since the attorney has not been made aware of all of the facts and has not reviewed the pertinent documents. Further, this post is for informational and educational purposes and does not establish a lawyer-client relationship.
