Is this for the threat, or are they pursuing the domestic violence charge?
A threat made over the phone when your ex is withholding your kid? I can understand that. It’s wrong, but I get losing your temper and saying something terrible.
A 6’10” guy (or anybody) choking his girlfriend? That requires jail time.
The DV allegations may be true, or they may be fabricated. The threat is obviously real and provable.
