I experienced this many years ago, under a different name (and using a completely different account and email address).
I asked for help from mners because my husband had just hit me in front of the children, and I had called the police. I was told to leave IMMEDIATELY, and warned about all sorts of dire consequences if I didn't. It frightened the life out of me.
Advising me to leave in the middle of the night and go to a hotel wasn't helpful. I had no money. A refuge would have been dreadful, and so stressful for the children. My eldest had special needs which meant I needed to stay in my house (eventually I got an occupation order, and I'm still there 3 years later). There were no friends or family members I could stay with that night.
I got so busy telling everybody on mumsnet to calm down, that I almost started minimising the situation. They were telling me I was seriously physically unsafe that night, and I knew I wasn't - I knew that ex-dh had burned himself out with that single act of violence, and that I had time to make a decent escape plan. I nearly failed to recognise the actual risks - which were increasing emotional abuse for the children, threats of suicide and all sorts of other weirdness.
I've learned a lot about domestic abuse since that time. Being strangled is a risk factor. Threats to kill are a risk factor! (I saw a thread today where an op disclosed threats to kill, and some posters were advising her simply to change locks and throw his stuff out, without making it clear that a police record of his abuse would help to protect her and the children in the long run).
Maybe I'm not being very coherent, but this is a subject dear to my heart. I've seen (and experienced) some fantastic support on mn, and some very sensible advice, but have also seen some quite hysterical posts which aren't helpful. A woman who is on the process of realising that her partners behaviour isn't acceptable is not always ready to take immediate action, and real life people with some training (women's aid, ncdv etc) are probably much better placed to help her anyway.
