Seriously. I used to be a lawyer, and on the basis of what the victim told me, in tears in DP's living room, while she couldn't remember the specifics there was enough that the CPS would consider a prosecution in the public interest. Not going to get into the specifics but I think she's doing herself a disservice with not making it a police matter. There's also some backstory, bad character evidence, that puts me beyond reasonable doubt that it'd not take much of a following wind to secure a conviction.
She, on the other hand, has gone back to being in a relationship with him. Brought him along to the venue DP and I were at last night and asked me not to be 'difficult' with someone I'd cheerfully thump the living daylights out of on the slightest excuse. She made pretty much every rape-culture excuse in the book for his conduct, and I finished by asking her not to bring him to anything where I'd be present, as I wasn't willing to keep the company of the likes of him, or compromise my principles about such matters.
Am I being too harsh on her? (Him I'm not concerned about, his just desserts are four to six years in jail and a lifetime slot on the Sex Offenders' Register, me snubbing him in public because DP has asked me not to beat him into a thin red paste is NOTHING.)
