My question involves criminal law for the state of: Texas

My lawyer told me today that the prosecution was "leaning towards deferred prosecution." My lawyer failed to clearly explain to me the technicalities of accepting such a deal.

If accepted:

1) Does anything go on my record at all? Would I lose my secret clearance or have trouble renewing my secret clearance?

2) Under what conditions can the case be re-filed? If I get a traffic ticket? If I am caught urinating in public in the future? or something as serious as the original charge - Assault with injury DV?

3) Should I even be considering deals when I know for a fact that I did absolutly nothing and know there is no evidence for such beyond a police report that is simply a written her word against mine, no pictures, no marks, no bruises, no doctor visit, nothing?

4) Are there any charges or fees?
