Should I text her again? When to follow up and when to stop

If she wanted to text, she would. Phones are always in reach. The usual reasons she's not replying. you came across as trying too hard, you asked something that felt like work to answer, you texted at an odd time and it got buried, or she's not that interested. Sometimes it's just logistics. But silence past 24 hours is a signal.

The length of silence matters. After 12 hours, you might have just missed her. After 36 hours, she's seen it and chosen not to reply. After 72 hours, texting again is starting to feel like you're chasing. Read the gap before you move. If she went dark after you were trading messages, that's a harder rejection than if she never replied to an opener.

Don't rephrase the old question or ask the same thing differently. That looks like you didn't hear her silence. Instead, introduce something totally separate. A funny observation about her profile, a reference to something she mentioned in a conversation from days ago, a low-stakes plan suggestion. The new text has to give her a reason to engage that doesn't require her to acknowledge she ghosted.

Keep it shorter than your first message. Short texts are easier to reply to and they look like you're not wound up. The tone should be light and forward-moving, not apologetic or needy.

If your first text got nothing, wait at least two full days before sending a second one. This isn't about playing games. It's about giving her enough time to actually miss her phone or have a second to breathe. Texting back after 6 hours looks like you were sitting there staring at your phone.

If the second text also goes unanswered for 24 hours, you have your answer. She's not going to reply. Don't send a third message. That crosses into making it her problem. Delete her number or mute the thread and move forward. If she ever does reply weeks later, you can engage with her then. But right now, continuing to text is just hurting yourself.
