This.I don't know why the assumption is she went off in a strop.
Sounds to me like she wanted no strings sex. You said no and she moved on.
Strong woman who doesn't want a man to chat, just a quick shag.
You obviously wasted her time, scared of the fanny.
If a bloke tries to get a lass over for a quick shag and she says no, and he then ignores her, he's not labelled vulnerable, like in the op.
He's just a fella wanting a shag.
No different here.
It's obviously not what you want, she'd have ripped your heart in two.
