That sounds horrible... police often take sides depending on gender and age etc so men are at a disadvantage when they get false allegations made against them. I had an ex once and I was with her for two years, she drank heavily and she was very abusive towards me I wanted out of the relationship but every time I would attempt to leave her, she'd go to the police and say I'd hit her, she also broke her windows once on a drunken rage... anyway I had to keep getting back with her. She would often make threats that she would do this and that if I left her. I was really stuck until I met somebody else and I was able to get out of the relationship but not easily... she tried to have me shot... she had gone to the police and told them I had a gun in my house... the police raided my house while I was handcuffed in the back of a police car, they found nothing of interest and that was that. That was back in 2007
The police will always take a woman's side by default.
Police also put things on your record that have no basis, not a criminal record but a police record which I don't think is right.
