Should I seek a protective order?

A protective order is considered to be an extraordinary remedy, as they impose serious restraints on a someone's personal liberty.  So, while it's not fair to say Judges are reluctant to grant them, they will want to see clear evidence that there is a reasonable apprehension that someone may be harmed.  

Plus, if a Judge gets the idea that you sought a protective order without proper justification, it can have a negative impact in subsequent litigation (e.g., a custody trial or divorce hearing).  

An experienced Family Law attorney will be able to advise you on whether the facts of your case warrant seeking a protective order.
