Please let me explain, is really important that I perhaps explain a bit, but I do not think is priviledged.
My parents and also my husband parents supported us to get excellent education and payed for our tuition as well as helping in the early stages of our careers.
For me and my now husband, our parents provided, each.
During University: Pocket Money and Rent, me in turn I got scholarships and distinctions
Early stages of my career: Rent. Me - saved fiercely and in 2 years I bought my first appartment. My parents gave a significant amount towards deposit money.
Then fast forward getting married:
Parents payed for honeymoon; no cost on their end for our wedding; wedding gift went all exclusively in pension savings.
Me and husband saved and bought a larger apartment before getting married, whilst his apartment was on rent and both were in good jobs; We took our parents toghether in one trip/year payed exclusively by us, as a rule.
When Baby arrived:
Each of our parents opened a Junior Bank Account and placed a very significant amount there;
We opened a Junior Bank Account for our DD with a very reasonable amount and we save each month too.
We bought our first House in central London, parents payed for stamp duty and furnished all house;
We go each year in one holiday toghether and we pay for that exclusively.
I pay private insurance for my parents and my husband for his. I oferr 200£/PM to my parents and this is just a little help to ensure they can enjoy their pension. I invite them for dinner at least twice a month and we go out at least once a month. I take my mum to all her medical appointments.
My mom drops and picks my daughter from school voluntarily as she absolutely adore my DD.
And now, yes, we are in a good job, but that;s because our parents sacriced for us almost half of their life. This is not privileged, it was a sacrifice on their end. Also, see example for my husband, same case.
Going back to the original poster:
An almost retired nurse has a salary that is approaching £57,102£ and that is just for a basic nurse with no additional qualifications.
She said she reduced her hours to 30pw, so let's just presume a very low salary as alleged. Bare in mind that nursing staff have a lot of benefits: time off after shifts in which you have time to get extra work (one relative that is a dialisis nurse makes a wooping 150.000£ after taxes from locuming, this is because she works a lot). Let's just assume that OP has restrictions that cannot let her work extensively - at least she can work an extra premium shift to boost her income, there is always staff shortage - she can do as she pleases with that money.
Also, now, how she will manage after her daughter her will move with her BF? Will she take a lodger or move out to downsize?
Is not yet clear if the OP has issues with the behaviour of her daughter or she simply cannot afford to live in that area alone.
I am not saying that all the parents should/can do the same, but at least family should come before money and there are always ways to solve a problem.
I do hope OP finds a good solution for her and her daughter.
