Hugs and dating
You should watch for her additional facial expressions after that in order to know for sure.
It is a type of hug in which the woman might act like she hugs you yet without touching you. If you have a date with her, and she gives you this type of hugs, then it may means she is not really into you and maybe will not ready to go out on the second date with you.
Just a little less or more pressure of a hug can vary its meaning.
When you touch and hug a person in a specific place, it could mean something different than hugging and avoid touching that person anywhere.
This unreciprocated hug is when you hug her, she lets you but her own arms are just limp on hẻ sides with her body getting stiff.
When she gives you such type of this hug at the end of the first date, then you should not expect the second one. If the woman hugs you using one or two of her arms, with an extra lovely and squeeze smile, then no matter how she feels about you, you could expect the second hug.
Also, it could mean something else, particularly in a situation where she is not really in a hurry, yet just want to get the hug over with.
