I'm actually really interested and heartened by the posts from curry and sockamnesty showing support for these services. You're definitely making me think about it differently when I'd previously perhaps taken a bit of a knee jerk reaction. Thanks for sharing your experiences. 
The issue of framing is helpful. I have done it myself on MN threads. Recommended that posters read books about DV because they outline the real signs somebody is changing. It isn't a lie, because the books I've recommended do. But it's a selective truth because I know that in reality the chances an abuser will change are extremely slim, and the poster won't find what she wants to hear within the book. However, information such as that contained in these books can help empower women and enable them to see their situation more clearly.
I am still worried it's a crap advert sending dangerous validation, and I do worry about services which specialise in this if they're receiving separate funding from other DV services.
It also makes me feel sceptical that we're seeing these services come in just as other DV services are really feeling the pinch from cuts and have already been reduced massively, because it does feel, like I said earlier, as though there are massive gaps and they're being filled with - basically anything. It is heartening to hear that (at least the services posters here have experience with) are being run by people who fully understand the mechanisms of abuse and have women's safety at their forefront.
I do still have some concerns - that if services such as these become more popular or are shown to be successful, that less well-informed people may be tasked with running them, perhaps for example religious organisations which value the unit of marriage more than women's wellbeing might start offering similar kinds of services and for this to legitimise that. What's niggling at me too, (sorry to make this political, I've really tried to hold off this comment,) is also that a narrative that staying together is better than splitting up fits very well with a certain conservative ideology, and I would hate that to be where support of this type goes towards, or used as justification for more cuts to women's DV services. I can fully believe that right now it's harm reduction and only the same kinds of safety plans etc that Women's Aid and so on already encourage women to make even if they do not wish to leave, my unease over this is where it goes and particularly what message it sends if this ends up being the predominant message.
