Someone once asked:
"How do you tell someone that you really like them without flat-out saying it?"
She was really starting to like this guy see, and she wanted him to know, but she is shy and didn't know quite how to go about it.
Like everyone of us, she is afraid of rejection, and so she hesitates, and considers letting it go...
I think she should tell him privately that she would like to get to know him better and invite him to dinner (that she makes) at her place and a DVD.
If a man is interested, he will not say 'No thanks' to this invitation. If he does, that's all you need to know, he is not interested in you.
Men are simple and direct, for the most part.
If you approach them with calmness, clarity and directness, most men will respond positively.
Unless of course they just aren't interested.
Either way you find out where you stand.
