When you like someone does your eye necessarily dilate. I heard if someone likes you their eyes will become bigger. but when I am with my boyfriend his pupil is really small.

When pupils dilate they become smaller, which is often due to light or focus. When we are focusing on something, our pupils will dilate in order to allow less distracting, peripheral, light. When we are focusing our attention on something, or someone, this will often happen as well, which is why, when we are paying attention to someone we like, or love, our pupils will often dilate. If you pay attention, you will find he is so focused, he is probably switching back and forth between each of your eyes, or other aspects of your face that he likes, rather than focusing on your whole face, which requires more light.
It is the eyes that led to the development of the shutters and lenses on cameras, which coordinate to determine how much light, from where, gets to the film, to form an image.1
