Sorry to hear what happened to you.Were all well aware that it happens both ways, but just looking at several media outlets with regards to the AH/JD case and they are all very heavily stacked in her favour, I also think society still has a problem with regards to domestic violence vs men, as you said the police were shocking. That needs to change as they are often the first port of call.
I'm aware of plenty of cases where abuse has happened vs a man and when the police turn up they are the ones who end up in the police car as the women bleets on about abuse when they caused it. It happened to me over a decade ago and the stress and anxiety caused by literally having to bare my entire life out to the police to prove my innocence because she outright lied was just ridiculous to say the least. That feeling like your a criminal when you have done nothing wrong, just because she said something without any evidence to back her up. All I can say is thank god I have good friends who have known me for decades.
My brother in law was going through a marriage break up with constant arguments. In the middle of a big argument he had the foresight to call me and ask me to come over "just in case". Sure as eggs are eggs she slapped him across the face (he was sitting down in a chair with her leaning over him screaming) and then she called the police alleging he had been hitting her. I have no idea why she didn't think of me being in the room.
It backfired on her because after talking to all three of us they arrested her, rather than him, to separate them for the night. I don't think he ever pressed charges so there were no long lasting consequences for her. But at least it didn't go the other way and him being arrested simply on her false accusation.
