Is a protective order valid across state lines?

Location: Virginia, Florida

To make a very long story short, I (F19) am considering getting a protective order against my ex boyfriend (M19). I live in Virginia, but I go to college in Florida. If I get a protective order while I’m home for the summer in Virginia, will it still be valid in Florida? The officer I spoke to said I might have to get another order when I get back to Florida. If I don’t, is he still barred from reaching out to me? If I get the PO while in Virginia and he reaches out to me when I get back to Florida, can he still be charged with violating a protective order? TIA!
