Will a letter help?

I am in the middle of a domestic violence case in Adams County, Co with my fiancé. I am carrying his child and this has been a stressful time for us, which is why this happened. He is currently in therapy and we both want him to have little to no jail time in the matter so that we can try to repair our life. Although it wasn't me who called the police, they won't let me drop the charges. My question is, will it help him or hurt him if I mail a letter to the judge/D.A. with my feelings about his sentencing?

Any light that can be shed on this subject would be helpful. Thank you!

Try speaking to the DA, They have the right to continue to pursue the case on their own (even if you don't want them to) but if they feel this was a one-time incident and will never happen again--they may drop it. They want to make sure no abuse is continuing if and when you two are back together.
