My question involves criminal law for the state of: North Carolina - Domestic Violence

My boyfriend and I have been together for three and a half years and have lived together for the past two years. He has a history of emotional issues and has been diagnosed with a bi-polar disorder. Over the past year he has hit me on several occasions but I chose not to press charges, begging him to seek professional help for his problem. He began counseling a few months ago and I have seen several improvements in his behavior. However, he recently hit me again and this time I had him arrested. The relationship is over and I have no hopes of it continuing. We also plan to live separately in the near future.

What I am concerned about it how the sentencing will work for this due to it being his first offense. I know that the maximum sentence is 150 days in jail. We are both college students and he is an excellent student with great grades. I am curious as to the likelihood of him receiving probation, community service, anger management etc. in the place of serving jail time. I want him to get the help he needs but I'm terrified that jail time will damage his college career. Any help?
