How do you know when your crush eyes dialated?

When your crush's eyes dilate, you might notice their pupils become larger, especially in low light or when they are feeling excited or interested. This physiological response is often a sign of attraction or emotional engagement. Additionally, if you’re having a meaningful conversation and their gaze seems intense or focused on you, it could indicate that their pupils are dilating due to interest. However, it's important to consider the context and other body language cues as well.
