Needing to vent DV

Im not really asking anything just needing to vent!
Back in February I got into a fight with my brother and it became physical. I called my partner up at the time and he came and got me. He tried to pick a fight when he got here with my mum and brother banging on the window of the house to let him in calling my brother out for a fight telling my mum to suck a dick. He then put me in his car and took me to the police telling me that I have to be protected. The police asked if I waned to take out an AVO and my partner said yes for me. I had no idea what an AVO was or meant. Later that night when getting to his house I was lying in bed with him and as I went to sit up he elbowed me in the eye it was hard too I passed out and my eye was so black and puffy. He told me right away that i can tell the police my brother did it and it looks good for the AVO.
Once taking out the AVO it all came out i was trapped he was the violent one. I was manipulated controlled and had no where to go now i wasn't aloud near my brother who lived with my family.
Fast forward a month and i find out im pregnant. Fast froward another month and he starts to physically assault me. I was scared for mine and my unborn child's life. Every time I tried to leave he said he would kill him self. He also broke my keys and phone one day after assaulting me and i tried to leave i was totally trapped.
When I finally got my keys fixed a month later i ran. My eye was still sore and i could not have it xrayed as i was pregnant.
I got it xrayed last week after having my baby and it is broken still i wake in the mornings and it is puffy and black some days. I Reported it to the police today and they told me it is to late to press charges! That i should have reported it when it happened but how could i when i was scared of him isn't that what happens in DV. I told them i would like to report all the other times he assaulted me (which i gave statements of when i left and took out an AVO) they told me that because i didn't do it on the day that i cant ask for an assault charge, how could i when i had no phone and keys as he broke them! As soon as i got out i made a statement. They pretty much told me sorry they cant do anything!! So if a women is held hostage and a month later escapes she cant do anything cause she didn't do it when she was being held hostage?!? It is not fair he gets to walk away from it all and not be charged. And now i am suffering. He now has a new girl friend and i can see the pattern already she posted on her Facebook today that she is deleting her account. Why she has just finished school young girls love face book. He made me do this and his ex before me. I tried to warn her commented on her photo on instagram of a ring he gave her for xmas which was my engagement ring told her that it was mine and to be careful and she blocked me. How is it he is the abusive one and the police are letting him off and now he has a new victim. Do I go to someone higher and say i couldn't report the eye because i couldn't have an xray as i was pregnant? Im so angry where is the fairness and support for DV victims. He has broken the AVO many of times and they dont care. He even broke it in front of the police when i was collecting my property he was meant to be in another room and he wasn't he talked to me and cried to me (crocodile tears) he even proposed to me with that ring his new girl is wearing and the police just stood there when leaving they told him its okay and to call his mates for support! I reported this and nothing! I am so over it. The police are shit to put it bluntly. How is there a time frame on reporting assault when you haven't been able to escape. Ive finally (like many other women) worked up the courage to come forward and nothing is done! In my small town DV is very pushed here there are signs every where, town meetings but it is all for show to make the police look good because they just dont care!
