Our pupils dilate when we are seeing something stimulating or we are in low light. If we are aroused our pupils dilate in order to take in more of our pleasing surroundings. Often during courtship pupils stay dilated. You can tell when someone is aroused by looking closely at their pupils in constant surrounding light.
In theory, yes. When we dislike someone, our pupils narrow on them and when we like someone, our pupils expand. Women manipulate this using eye make up as well as darkening the lights to set the 'mood'. In a darker room, pupils expand to let in more light and as a result it seems as though you like the people in it more. So I would say yes, if you are in love your pupils would generally dilate. However, do not use this to decide if someone loves you or not.
