In the first place, has the guy confess to her he likes her?
Some women are smart, they pretend that they don't know anything,
but in reality, they can "feel" it. Its just that probably the guy
has never make it plain to her, and u did, that's why she
considered ur proposal. Had the guy told her he like her, she would
probably have said the same thing to him.
I really hope that u and her have a good ending though.
