Spuddington, how many hours a week do you work and are you in an isolated part of the country with no jobs locally or a town/city? If you are working full time for
I can see how with £7 in the bank you feel you can't just walk out, so I'm not going to debate with you about that. However, although your husband is an utter cunt, you are NOT trapped - you are a strong and resourceful woman who has the power to change her situation.
Firstly, make sure that you are getting everything you are entitled to: www.gov.uk/benefits-calculators
Secondly, it's the 10th of August. What can you do by the 10th of September to improve your monthly income?
What are your skills now? Did you go to uni? What do you LIKE? Do you have any office skills? A job in an office would pay more than you are earning right now and working days would be better for your daughter anyway.
If you have any skills that you could build on, do it now, for your daughter. There are many online (and face to face) courses that you could do to get certification in different areas to boost what you have already and make you more appealing to a better employer.
You don't have to become a Bitcoin guru or a radiologist in 4 weeks - you could take in ironing, slot some hours doing cleaning in around nursery - anything to build up your weekly earnings so that you don't have £7 in your account this time next month, but £100, or £250. If you were able to increase your earnings by £75 a week (7 or 8 hours of cleaning would get you that), you could have another £25 for food during the week, and £50 to squirrel away and you'd have £1000 by Christmas.
If you have a bank account and payslips showing continuous earnings and savings for three months, and £1000 for a deposit (assuming you're not in London!) you could get a flat for you and your daughter and start divorce proceedings.
So that's four tasks:
Find out what you could be getting from the government to ease the pressure slightly.
Get a better job, and see what you can do to "upskill" yourself (Udemy has a bewildering number of courses to train in mainstream office skills, for instance - take a look - when you sign in the courses are all much cheaper).
Try to increase your income by £75 a week through some kind of nixer (or the better job) and start putting £50 a week into a secret bank account that your husband doesn't know about.
Get out by Christmas.
