What will happen if i am charged with disorderly coduct during restraining order?

I recently changed my number. Noone knew wat it was except my mom and sister. I have a restraining order against me and decided to act as someone else and text that person. They thought I was threatening them so they reported it to police. (I went to jail last week for violating the order by contact through calling and texting) wen I went in, I guess I gave them my new number. So wen the person reported it, they ran the number and said "thats the number that ******* gave us as his contact" I heard about this and called the station and tried explaining to them that I gave them the "wrong number" on accident. I said "that number was texting me too, and I just got a new phone and didn't know ky number. So wen I looked at my phone wen I was there, I was nervous and accidentally read u that from a text message" but I got a new number two days ago. I'm being charged with disorderly conduct for this, and have already filed for diversion bc of the last time I went to jail, and its pending. wat can they do? Cuz that's not my "number" now. Can they tell it was mine back then? The person didn't report til yesterday, and I changed it two or three days ago. Wat could happen? Do I need a lawyer? how can that prove it was me if I no longer had the number wen they reported it?
