This will be outing, but..
I was attacked three times by an exGF before I finally left. I didn’t retaliate at all, although I obviously held her hands to try, unsuccessfully, to stop her scratching my face up.
I reported at a police station on the second occasion, but the two officers at the desk weren’t interested, despite the very visible and extensive cuts and bruising to my face and arms.
On the final incident they had to detain her (she tried to barge past two attending policemen - both very big blokes, much bigger than I was - to attack me again) and it took six of them to get her in handcuffs.
They STILL didn’t charge her and just allowed her to sleep off the booze in a cell overnight. I had to pursue my own injunction, without any help from them and pay for it myself. I could not have been worse served by the “system” (and unfortunately that still seems to be a feature, for men and women) and none of those incidents will have been recorded as DV or even common assaults, which has left me very dubious about all the stats that get flung around on this subject.
I stayed with her at first because we’d been together for a few years and she had things going on which I was sympathetic about. I still thought I loved her. Thank God we hadn’t had any kids or I would have stayed anyway.
I also didn’t have any close friends where we were living and felt too embarrassed to open up to my family or anyone at work. Had I had someone to really talk to then I’d have been out of there sooner (at least I hope so) and I don’t think I could stand by and say nothing if I saw a similar situation with any of my friends.
