That's a crappy situation. Don't 'snap' at her about the whole deal, you'll ruin everything. I spy you're being tested by her. If it were me, I would say that I really feel mislead by how the night was setup(home-cooked meal, choice of movie, being alone, etc.), that my feelings were hurt, and quite frankly feel insulted. If the two of you are good enough friends she 'should' be sensitive to you sharing those feelings and be more open and up-front about what's going on from her perspective.

She could've had a night like that with galpals if her intensions were to eat and watch a movie. If she is really so naive to think that the way the whole night was setup was totally innocent and that a guy wouldn't see it as being led on, then like dubster says "KICK ROCKS BISH!"
