Help with a cellphone "spoofing" situation

Hello all and thank you for your time this is a fascinating and cutting edge field.

I have a personal situation, I work for a Company that works in banks, doing IT services etc. That is only important in the implications personally of what I am about to explain. As I need to maintain a clean criminal background as they don't provide keys to banks after hours to anyone.

My Ex and I have split. She obtained a Temporary Restraining Order (TRO) for "Domestic Violence" which is completely untrue and the judge made mutual after stating there is NO evidence of domestic violence.

Now the instructions in the order both the TRO and the RO are NO contact via everything, cellphone text included.

Now here is what I require help with. On one eveing when the TRO was in effect, I am asleep and at 430 AM I am awakened by this banging on the door, I respond in time to find the police driving away. I found that weird and had no idea what was wanted. We were due to be at the RO hearing the following day, and I was to be out of town so my attorney was going in my place. After the hearing the Ex's new boyfriend and the Ex approach my attorney stating that I had violated the TRO and RO contacting my Ex 16 times immediately following the hearing. They also went to the local police department who called me asking why I was texting her and violating the RO. I told them I wasn't. But bottom line here, is had I openned the door that morning at 430 AM I would've been arrested for violating a Domestic Violence Restraining Order, held in jail, missed my plane flights and most likely been fired from my position. As many of you know there are many men's lives destroyed everyday by women who falsely accuse them of such acts in revenge.

So what I have done was contacted my carrier, it is actually my work cellphone carrier and they show no record of calls or texts to my Ex's number. What is occurring apparently, is the Ex's BF is "spoofing" my work cellphone number, or cloning, but my guess is "spoofing" text messages to her cellphone making it appear to be me, in an attempt to get me arrested on a domestic violence charge, fired and all that goes along with it. This type of behavior should be criminal on many levels, I live in a small town in Northern Nevada, that may or may not care to chase this down, but this type of behavior needs to be prosecuted. Any suggestions of how I need to go about getting the information to prove it is these two individuals using their own devices to commit false police reports, violating US Federal Law on "spoofing" etc?

Sorry if this is a bit disjointed if you have any questions please feel free to ask.

Thanks in advance.
