Under Florida's domestic violence law, Florida Statutes Section 741.28,
Quote Quoting Florida Statutes § 741.28(3)
"Family or household member" means spouses, former spouses, persons related by blood or marriage, persons who are presently residing together as if a family or who have resided together in the past as if a family, and persons who are parents of a child in common regardless of whether they have been married. With the exception of persons who have a child in common, the family or household members must be currently residing or have in the past resided together in the same single dwelling unit.
So the fact that you don't currently have a relationship does not of itself rule out domestic violence charges. I suggest working closely with your lawyer, who is the person in the best position to estimate a possible sentence if you are convincted or choose to plead guilty.
