She ignored your message but she's still active on the app

A read receipt plus active status tells you very little on its own. She saw your message, she's on the app, and she didn't respond. That combination usually points to one of a few things: your message was easy to read and hard to answer, she intended to reply and got pulled away, or she's keeping several conversations warm and yours fell to the bottom. Interest is more likely to show up as a slow reply than as silence, so a long gap with no follow up from her is a real signal. Pay attention to whether she's been replying to other matches or to your past messages before deciding what this one means.

The question worth asking is whether the conversation had momentum before this. If she was sending longer replies and asking things back, one unanswered message is noise. If the thread had been thin from the start, it may just be fading. Don't read the screen more than the evidence allows.

When you do follow up, the job is to lower the cost of replying. A question she can answer in one line, tied to something specific from her profile or your earlier exchange, works better than a message that asks for her opinion on something big or demands an explanation. Keep it light and self-contained so it doesn't read as a chase. Avoid referencing that she didn't reply, avoid sarcasm about it, and avoid repeating the original message word for word. The reply should sound like a fresh, relaxed thought rather than a reminder.

If you have a new reason to message, such as a photo, a link to something she mentioned, or a plan, use that. A new hook gives her a reason to answer that isn't guilt about the old one.

Send your follow up in the afternoon or early evening when people usually check their phones, not late at night when a message can feel like pressure. After that, wait a few days before sending anything else. If she answers, keep the energy matched to hers and let the conversation find its level again. If she doesn't, one more light message after about a week is reasonable, and that's the limit. Two unanswered follow ups in a row, with no reply in between, means she's not engaging, and continuing will only make you look desperate and make it harder for her to say no cleanly later.

When you stop, stop completely. Don't send a final message explaining why you're done, don't leave a comment on her photos, and don't move the conversation to another app. Unmatching or muting is a fine end to it.
