What is considered voilent contact when on probation?

I was placed on probation for disorderly conduct and the person i was ordered to have non voilent contact with now accuses me of harrassing! but its not like that at all! We have a child together and mostly when contacted its about our past relationship or child! but i just want to know even if he accuses me when they just come lock me up? bc to my understanding even in the txts we have sent back in fourth i have not threatened him yes ive called him out his name but HOW IS THAT VOILENT CONTACT?
