A lady who has a repeat violence restraining order on me is lying to police and they are listening to her!?

Long story short, my boyfriend is still legally married to this lady who works for one of the local pd. She went and got a repeat violence restraining order against me and has been telling officers I call her snd threatin her. I have not called this lady and the other day I came home, looked on my caller id and saw that she called my house phone 3 times, so I called the cops to take a report because I plan on trying to get this order removed because there is no reason for it. The sherrif showed up to take a report then the local pd who was out of jurisdiction came and said he was the one who called from her phone and they have two investigations going on me, one for aggravated stalking and I am not sure what the other is. How do I stop this bs and allegations against me? I am a single mother attending college and work full time and my boyfriend has no contact with this crazy lady what so ever. I have tried reaching out to Internal affairs but is always turns back onto me! I feel so violated, the local police also asked to go thru my purse and wallet and i said no and took the cards out for him because he said Ithey think I used a card to call her off of my boyfriends phone. The cop grabbed my wallet off of the table that had all of my cards on it which I told him in the first place not to touch it then he was in the dining room and my bf was in our bed in the bedroom which you can see from the dining room and the officer said his name and asked him to come out there and my bf said no because he knbows they are full of bs since she works for one of the local pd and the cop walked right into my bedroom and started harrassing my bf. What on earth do I need to do? This is so unfair and ridiculous, I feel like I need to protect myself from the police. Help please??
