OP, I understand completely how maddening it is that your husband left you alone at night. My ex-husband was completely oblivious that I could ever be in any danger. It makes you feel under-valued and unseen, and there was something that was a unique turn-off about it. A man not doing one of the few basic things that we often depend on them for, like physical protection in some situations, just made him seem like a giant baby. None so blind that will not see. He refused to walk me home once too. You'd think men would know better after that terrible Sarah Everard case.
So I get it. I really do.
BUT. You really are in danger just hanging out on the cold and dark at this time of night. If there's a pervert around, you are ideal prey. Please, please think of yourself and get home or somewhere safe as soon as possible.
Hypothermia is also a real risk, and it creeps up on you.
Just because some oaf thinks you're not vulnerable, and thinks it's OK to leave you alone at night like this, doesn't mean he's right.
Please, please think of yourself and get a cab.
If you must make a point, go to a nearby hotel if possible.
Just get yourself off the streets. You are precious and important and are too valuable to be left alone in the dark, even if that oaf back home doesn't think so.
Pleeeeeeeeeeeeeeease get a cab!!
