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

I am a women charged with simple assault and battery using non aggravated physical force. I was arrested and later on released on bail.The papers that I got mentioned do not harass, assault or intimidate victim but not mentioned that I should not contact him. Though, I am not living with him anymore but I called him 3-4 times in a span of week and he was fine with me calling him as I always asked him in the begining if he wants to talk. It seems now he switched off his mobile. The last time I called he was in the office and he irked me by being rude in return I also lost my temper. I have no idea what this could mean if he has recorded this talk to show that I am still harassing him.
