I have to say at 5 4 and a UK size 10 US 6 to 8, I look larger because my frame is so tiny. Not carrying a lot of extra weight and I work out a lot. I am 126 lbs but would look better at 120 lbs. After that the face goes gaunt.
It's my body type.
I am healthy now with 23% body fat, so mid range.
I wouldn't fit your definition of petite or skinny, not many women would at an older age. And generally a bit of shape can be gorgeous in later years. It's a compromise between face and body.
It can Change too, 3 years ago 30 lbs heavier as a result of ill health, and who knows what would happen in menopause to exW!
It's health that truly counts and that is mental health too. If NG isnt your type after a couple of dates then she isnt. You learned something important, but she isn't a substitute or clone she is her own person.
I like Ginger idea in exploring your type, moving beyond the familiar comfort zone.
You might be surprised.
