How do I respond to "I'm gonna shower"?

A message like this is almost always a status update. She has been sitting in a conversation, she has somewhere to be or wants to go to bed, and she is telling you the chat is pausing. The tone is usually flat on purpose, because she is not planning a reply right now. Read the rest of the thread before deciding how much weight to give it. If she has been replying quickly and asking you things, this is a normal pause. If she has been giving one-word answers for a while, the shower is more likely a convenient exit, and your reply should be shorter still.

The mistake most people make is treating the message as a test. There is nothing to pass here. She doesn't need you to be fun, impressive, or sad about it. She needs the exit to be easy.

The first kind is a short send-off with a light callback: a reference to something she said earlier, a wish for her evening, a reason you're glad you talked. It works because it shows you were paying attention without asking her to do anything. A draft is this kind when it names one specific thing from the conversation and closes there. It should leave out any question, any compliment about her, and any suggestion of plans.

The second kind is a simple acknowledgment that matches her energy. This fits a thread that has been short or a little lukewarm. It is one or two words, a sign-off, nothing more. A draft is this kind when a reader could not tell whether you were interested or just polite, and that is the point. It should leave out anything that tries to make the conversation feel bigger than it was.

The third kind is a mild forward hook: a small thing you plan to bring up or a question you'll ask next time. This works only when the chat has real momentum and you have something specific to come back to. It should be one sentence at most and must not require an answer tonight.

Once she has signed off, your next move is to stop. Don't send a follow-up in the next hour to check she got out of the shower. Most conversations pick up naturally the next day, and a fresh message that opens with something from the earlier chat reads as interest. If you want to bring something up, wait until the following day and make it a light reference to what she said.

If she doesn't reply within a couple of days to anything, you can send one short, low-stakes message that doesn't depend on a response. After that, if there's still nothing, let it go. A single unanswered thread is not a rejection, and continuing to message after silence turns a casual match into something uncomfortable.
