Get her talking again after you said you're done with casual

If she was keeping things light and then you said you wanted something real, her silence is most likely about the shift in the conversation, not a verdict on you. Casual conversations often run on an unspoken assumption that both people are in the same place. When you named the difference, she had to re-check that assumption, and that takes time.

Read her last few messages before yours. If she was matching your energy, asking questions, or suggesting plans, the silence is probably her thinking it over. If her replies were already getting shorter or she was dodging plans, the silence is more likely a clear answer, and you should treat it that way. Look for anything she said about her own life, like being busy, not wanting a relationship right now, or just getting out of something. That tells you what she is weighing.

Your reply has to do two jobs. First, it should confirm you meant what you said without making it bigger than it was. She may have heard 'serious' as a demand, so frame it as something you want for yourself, not a rule she has to meet. Second, it should leave the door open with no deadline attached. A reply that asks her to answer by a certain day turns a quiet moment into an interview.

Keep it short. A long message after a week of silence reads as anxious, even when the content is fine. Name one concrete thing you are looking for and stop there. Don't summarize the earlier conversation or argue your case again. If she answers warmly or with a question, you can get into specifics. If she answers with a short no, a clean thank you is the right move, and it leaves a better impression than any back and forth would.

Send in the afternoon or early evening, when she is likely to be free and you aren't writing from a stressed or late night place. Don't send a follow up the same day. One text that says what you need to say does more than two that try to fill the gap, and the second one usually reads as the first one's footnote.

Give her three to four days before you consider anything else. If nothing comes back, you can send one short, lighter message, or simply let it sit. Don't escalate with new explanations or check ins every day. If two weeks pass with no reply, or she answers with something that closes the door, stop. Silence after a clear statement is an answer, and continuing to message turns it into a worse one.
