I lives with my partner for 5 yrs and he assaulted me at least twice a week, if I got a break from it I knew I was going to get an absolute battering. However, I never had him charged, even for the broken bones. I would say that if it was the first time this had happened then by you being proactive and getting him arrested is a step in the right direction. Do not foget that by him having not touched your daughter, doesnt mean him beating you has not abused her. My son has changed tremendously since I kicked him out, and my youngest son still doesnt like men 6 months on. Its all very well to say get out while you can, but do not give him a second chance else you'll end up like me and start thinking its normal to just take it. You'll end up alienating everyone you love, and feeling guilty about what your kids have seen and heard.
