Hi, Hannah,
Wish I'd seen sooner...
Ok, so - you're definitely in an abusive relationship at this point. That means you need to leave. Injuries are an escalation, and throwing furniture, etc - he's off his rocker for some reason.
You need to work out a "plan B" and even "C". Need friends, need a destination, and maybe even a change of identity for a bit. Private transit, bypassing customs. Come back in a few months under the same name you left with, and keep using it...
I'd suggest working out an online presence to make contacts somewhere else. Use an anonymizer, maybe an online Amazon image with TOR browser? Don't know the costs.
Can you siphon money to your accounts? (You DO have a private account, right?) Can you do some day trading? (Risky, but if you're home anyway, you could play with small amounts and if you get good, you could then count on it as an income stream...)
If you have access to American TV, check things like "Bar Rescue" and "Life or Debt" for ideas on improving your situation while you prepare.
With a good bankroll, you can disappear one day with limited or no trace. And the child and dog can be added as appropriate (E.G., child traveling with a friend, so you both escape notice. Dog is shipped by friends - even if you have to FIND that friend first. Shared child care would be a good start, and there are "mommy groups" that should fly under the radar.
You'll have to get good at acting. If you play this correctly, you can avoid issues AND walk away clean, into a new life. You just need to figure out how to be his "dream woman" (even if you'd rather claw your eyes out) for a while. Hoard funds.... Cheat, even, in terms of taking cash out at the grocery store. Say, you buy £35 or groceries, take out an additional £20. Stash it for future. Do it once the first month, twice the second, etc. "Lose" the cash. KEY warning: DO NOT flash it around, EVER. You don't have cash, period. Prices are just going up.
I'd also ask, what skills do you have? (No need to answer, it's to frame things.) You had a job; where is there a demand that there's a lack of workers? You have a CV/Resume, so you can target such a location and see about getting a job in advance. (Women's shelter might help.)
This is a war, you have to either go in to win, or give up - and that can mean severe injuries, both physical and psychological.
Does he have external stressors? Bad job, family issues, money issues, drinking problem, etc, etc, etc? Anything you can use to leverage is essential here, E.G., a blackout period could allow all sorts of compromising video or pictures, which could be leaked to Youtube or such just when you're ready to leave... And used as a threat beforehand.
Keep in mind, though, that while it looks like you're a victim, more likely you are actually in control in a way: you enable his behavior, whether you mean to or not. You need to start establishing boundaries. Try looking here:

You need to re-educate him. Maybe give him mind-blowing sex, but only when he plays it the way YOU want. E.G., if he paws at your breasts, he gets lousy dinner and cold shoulder. If he holds them gently, caresses them, he gets a great blowjob and sex as well... Several times. Maybe then you push him in other directions; look up "Femme your Hubby," the mechanics are sound. (Whether you use it as written or not is up to you.)
You need to find ways to put him into an insecure, but not fearful or violent, spot. Then you're able to steer the relationship more. I'd suggest, too, that you look into prostate massage, as I understand it can overcome male urges - it's even more intense. Also, more sex, more, sex, more sex - even if you hate it, pretend, and let him think he's great, until he just can't manage it any more. He'll exhaust himself, especially if he's energetic about it, and he'll get more prolactin (bonding hormone for men) - making him more devoted. Also, make him stay in afterwards, instead of pulling out to clean up. Make him hold you for a while. I don't know if it's true, but supposedly it'll cement the relationship and make him more pliable. (I have only had one experience with that, but she was so special already I can't say anything about it's veracity.)
Keep up with us, just to check in, so we know you're OK.
And prepare for the worst even while you make him think everything's wonderful....
