I have an arraignment hearing for unlawful touching what should i except?

I have an arraignment hearing for unlawful touching. I called a attorney and did and interview but he just shrugged me off the phone without really answering any of my questions. Me and my fiance got into a fight over a text message saying he was cheating so i punched him in the face. We got into a tussle where he was strangling me with my own hoodie and threw me to the ground to get the car keys. Apparently none of that is written in the police report and only that I hit him which caused him great distress. im 5 months preggo. My boyfriend doesn't want any charges pressed against me or anything like that. He is going to show up at the arraignment. The attorney said he doesn't have to but maybe the charges would be dropped. I also have a no contact order. What should I expect. Could i actually face jail time for punching him? I don't even know what to expect or whats going to happen please help!! this was all a stupid mistake.
