I need a woman's advice.
On what subject do you need advice?
I met this girl yesterday and I like her.
Since relationships can be so complicated, it's understandable to reach out for help and advice when you are uncertain how to proceed. It's perfectly fine to ask for a woman's advice when you are looking to date someone.
I would like to date her but I am hesitant about approaching her.
That is understandable that sometimes we can be shy when meeting new people. It is okay to reach out for help if you need it. A friend could help give you confidence and boost you up to take that next step.
