How to respond when someone tells you you're pretty

Start by looking at how the compliment is framed. If it sits inside a joke, a photo caption, or a broader reaction like the light is perfect, she is probably playing and wants the chat to stay easy. If it stands alone and comes after a real exchange about your life, she may be signalling more interest and checking whether you feel the same. The grammar and punctuation tell you something too. Lowercase and a laugh suggests low stakes. A full sentence with a question mark at the end suggests she is waiting for a reaction.

The second thing to read is the history. Four messages in, a compliment is often a warm-up. Forty messages in, after you have both been talking about your weekends, it can mean she is ready to move toward meeting. Match the weight of your answer to the weight of her line. A light compliment wants a light answer, and a heavier one can take a little more warmth back, as long as you do not swing into a speech.

A reply that works usually does one of three jobs. It takes the compliment in a sentence and then turns to something you actually find interesting about her, which shows the attention is on her and not on the compliment. It returns a little warmth in your own voice, so she knows the comment landed without you needing to rate her looks. Or it lightly reframes the moment toward the conversation you were already having, such as the trip she mentioned or the thing she is working on.

You can tell a draft is one of these kinds because it has a clear second half that moves the chat forward. If the whole message is about the compliment, you are stuck. Leave out any explanation of why you took the photo, any joke about your face, and any question asking her to justify the comment. Those all shift the spotlight off her and onto how you feel about being noticed.

Send the reply within a few hours if you can, while the exchange still feels current. If the compliment came late at night, a short reply the next day is fine, but do not write a long considered answer at 2am that reads like you were up thinking about it. A quick response is better than a perfect one that arrives after she has moved on.

If she does not answer, wait a day or two before doing anything else. Silence after a compliment is often just the conversation ending naturally, not a verdict on you. If you need to say something more, make it about something new, like a question about her week, rather than returning to the compliment. Stop if she gives short replies twice in a row or changes the subject away from anything personal. At that point, let the thread drop rather than pushing for a second compliment exchange.
