She said she'd delete the apps but you can still see her online

Start by checking what you actually saw. A profile that says active now is different from one that says active 3 days ago, and a prompt answered an hour ago is different from an old profile that's just still listed. Apps often keep a profile visible for a while after deletion, and some people deactivate rather than delete, which hides them for a period and then reappears. Notice whether she has been chatting with you in the same window where she's visible, because that tells you she's using the app actively, not just forgetting it exists.

Then look at what she said and when. If she said she was deleting it and you're seeing her active the same day, that's a stronger signal than if you see a profile she mentioned removing last month. A quick, believable explanation is common here: she deleted and reinstalled, a friend set it up, or she left it running while she sorted things out. None of those are proof of anything. What you're reading is whether her words and her behaviour line up over the next stretch of time.

The worst move is to make this the subject of the conversation. Once you open with the apps, every message after it becomes about trust, and the connection you had gets buried under the audit. Your job is to keep showing up as someone easy to talk to. Ask about her day, share something real about yours, and let the rest of the exchange carry the weight.

If you do decide to mention it, mention it once, plainly, and without a question that demands a defence. Describe what you saw as a fact about your own reaction, like noticing it and feeling a bit unsure, and then leave room for her to respond however she wants. Her reaction is the information you're after. A relaxed, direct answer is a good sign. Defensiveness, vagueness, or a sudden change of topic tells you something too.

Don't make a judgment on the day you see it. Give the situation a short window, usually a few days, and watch what she does. Does she keep being warm and consistent, does she make plans, does she reply in the same way as before? Or does she go quiet, get shorter, or start pulling away while the profile stays live? The pattern of her behaviour across that window is the most reliable thing you have.

If you raised it and she gave a reasonable answer, and then things continued normally, let it go. If you didn't raise it and the profile is still active after a week while she's getting less engaged, you have a clearer picture and can decide whether to say something or move on. Stop waiting when you're clearly the only one putting energy in, or when her explanations keep changing.
