*Mentally healthy, NT, pregnant, homeless women do not, ever refuse a warm, safe bed for the night.
The help needs to kick in well before these women become sick enough to end up on the streets refusing what little help there is left to them and it needs to be adequate enough to prevent them becoming homeless.*
In my experience, it is because these beds are often not safe. When I was pregnant, and had fled my abusive partner, I was housed in a homeless hostel.
From what I have heard, pre-2010, most pregnant women got put in self-contained temporary accommodation, and any others got put in hostels which housed only women/ children.
When I was in there (2015), it housed everybody. Pregnant women, children, drug addicts, just released prisoners. Shared bathrooms.
I knew people who had been raped there. I lasted six days before going back to my abusive ex partner. Three days of weeing in saucepans at night and having my door attempted to be kicked through each night. To be robbed, I think - not attacked, but who knows.
I had a fairly good childhood, and no experience of living on the streets. But I can completely understand why for some women, they feel safer on the streets in a community they are familiar with, than a place like that.
I live in a major city, and have heard several horrifying tales of women who have been attacked in homeless hostels like the above. And you have to live there for 1-2 years (with your kids) before getting moved to a flat.
I was lucky, saved up and got given some money so I could leave my ex P again and rent a private rented flat, went to uni etc. But not everybody has these opportunities.
Please do not think that the accommodation they offer you when you are homeless is always safe, and these women are on the streets because of some mental deficiency or naivety or stupidity. I think if you believe that, then you are the naive ones, tbh.
