Unfortunately, they can still go through with the charge even if you want to drop the charges. However, as their key witness, they would need to have you testify, and your testimony may go against the charge such that he wouldn't be convicted.
The charge definitely does not seem to fit the crime in your case, and this really should be a misdemeanor
at most. There are many cases of severe domestic violence
that are still tried as misdemeanors, and also, abduction doesn't seem to make any sense either, as he didn't take you somewhere against your will.
At most, he should maybe have been charged with false imprisonment, for preventing you from leaving the house, but abduction is more like kidnapping
So, it is likely they would go through with the charges, but if he's got a good Defense Attorney or Public Defender, he should have a good shot at beating the charge.
