What to text when she says she's been catching up on sleep

Pay attention to how she has been texting before the gap. If she was sending long replies and asking you questions, a tired week is probably exactly what it sounds like. If she was already giving one-word answers and taking a day to reply, the sleep line may be a polite exit rather than a real explanation. Look at the shape of the conversation, not just the one message.

Also notice whether she offered the explanation without being asked. People who volunteer that they've been resting are often trying to reassure you they haven't gone cold. People who give a flat one-liner in response to a direct question about the silence are usually keeping things brief. Both readings are normal, but they call for different levels of warmth in your answer.

The easiest way to make a reply land well is to acknowledge the sleep in one short sentence, then move to something neutral about her. Don't dwell on how rough your week was, and don't turn her rest into a bigger story than she made it. A quick nod shows you heard her, and a question about her week gives her an easy thing to answer without having to re-explain herself.

Keep the question open enough that she can answer in a sentence or two, but specific enough that it isn't generic. Asking about one thing she'd mentioned before works well, because it shows you were paying attention and gives her a reason to talk about something she likes instead of the tiredness itself.

Send your reply when she's most likely awake and not in the middle of something she has to do. A tired person who gets a text late at night is more likely to answer with a sleepy one-liner or nothing at all. Mid-morning or early evening, when most people have a bit of energy, usually gives the conversation a better chance.

If you don't hear back, leave it alone for at least a day or two. A second message the same evening reads as chasing. If you want to follow up, wait until there is a natural reason to, like something you saw that made you think of her, and keep it light. If two or three messages go unanswered over a couple of weeks, the match is probably not moving forward, and it's fine to let it drop without a final message.
