I hope you were able to get some beneficial sleep last night, shades.
If the police don't make contact with you this morning, call them and ask whether he's been apprehended and, if so, ask whether he has been/will be released on bail and ask what address he has been/will be bailed to and what conditions, if any, must he observe while on bail.
Have you been allocated a dv worker by your borough's police dv unit?
If your h is named on your mortgage/tenancy agreement, it may be advisable for you to apply for ex parte occupation and non-molestation Orders asap. Your dv worker will be able to refer, or take, you to a solicitor who will have experience in making applications of this nature.
Any such Orders will be granted for an interim period, usually 28 days, pending a full Hearing of the matter(s).
The paramedics who attended last night will have checked for concussion; if your headache continues and you find yourself feeling drowsy or forgetful please call 999 and ask for the ambulance service so that you can be seen in an A&E unit - you can take your dd wth you.
Please bear in mind that you've sustained a severe shock, not just to the parts of your body he attacked, but to your whole system. Don't try to do too much over the next couple of days - stay in the warm, drink plenty of fluids, be sure to eat regularly - little and often if you can't stomach your usual size portions and, dd permitting, make sure you rest/nap during the day.
I know this is easy to say and not quite so easy to do, but try not to overthnk everything that has happened or get caught up in a maelstrom of thoughts about what may happen. Take each day as it comes and, until you feel fully yourself again, only do chores that are essential to your own and dd's wellbeing.
Last night you proved you're not lacking in courage and that courage, coupled with a firm resolve to create the life that you and your dd deserve, will get you get you to a better place sooner than you may think possible, honey.
