Oh @Idontknowwhattothink I am so sorry, this is just so horrendous for you. I have to agree with @ChampagneLassie, except I don't think that you have time to "get your ducks in a row". Just go before something too awful to even contemplate happens.
If you have no-where safe to go to with family or friends, then please turn to women's aid again, and if they can't help you then go and sit in the councils offices later today with your daughter, and don't leave until they put you in temporary housing for a night or two - preferably in a different town - and transport you there. After a night or two they will have hopefully been found you both a safe place for the two of in your own town, or even back in your own home, depending on what happens with your husband.
Are you able to tell us what the safety order comprises of OP? The trouble with anything like safety orders (but yes you were definitely right to get one, so that the police can act straight away if your husband threatens, or tries to harm you or your daughter) is that they will work well with perfectly sane and law abiding citizens, but anyone who has any disregard for the law, whether through mental health problems, or through just not giving a , probably won't let any restraining orders etc stop them from doing what they want.
I am not trying to scare you OP, well actually maybe I am, just a little bit, but I think you are already scared and confused enough, and I certainly don't want to add to your stress. But like you, I and the other mumsnetters here want you and your dearest daughter to be safe, and hopefully we can help you with that, by the very fact that we are not, and never have been, in love with your husband, nor are we invested in his welfare in any meaningful way either, so at the moment we can probably see your situation - as you have told us here - more clearly than you can. So I hope that at least some of our comments make sense to you, and can therefore help you with your decision making.
Once you and your daughter are safe, you can work with your husband's GP and the police, and hopefully a mental health team as well, so that if your husband agrees to their intervention they can try and find out exactly what mental health problems your husband is suffering from. For example, Dementia can actually change a person's character, so if they find out that your husband does have an early onset Dementia they would know reasonably well how he could, and how he couldn't, be helped.
I am only suggesting that you stay involved (but in the background) because you obviously still care about your husband, your daughters father; but if you are not up to coping with any of that then please don't feel guilty - you and your daughter have already been through so much, so if you only have the energy, and or the inclination to concentrate on your daughter and you, that is absolutely understandable, and probably the preferable option for you both. I, and I am sure many others here, will be thinking about you, and sending as many positive energies as possible xx
