Well there is always a way of leaving
For some women, leaving might literally mean being homeless. The council won’t house a woman without dependent children, and if hers are adults or stay with dad, she’s on her own.
Renting is a non-starter. I am a landlord, believe me, I know. My house, which is a very ordinary three bed terrace in quite a run down town in the midlands, has a rental value of over £700 p/m. Added to which, there are a lot of people hunting for properties and not many homes.
In the end it comes down to the woman's own perception as to which is the least worst, which will vary based in her own cost/benefit analysis of her relationship and of the alternative.
It isn’t purely about cost, it’s about practicalities.
My marriage is mostly happy. But if it was to end - I don’t want to lose custody of my children EOW. I don’t want to alternate holidays like Christmas, I don’t want to disagree about education, pocket money, chores, I don’t think anyone can say raising children in a partnership that’s gone wrong is easy.
But yes, I agree many of us percieve ourselves as trapped, because we don't want our freedom enough to move to a rented flat/bedsit and claim benefits or work a low paid job
You’d be lucky to get a rented flat or bedsit. And yes, it’s a miserable life that quickly leads to low level depression.
