What does it mean if a girl constantly snaps you?

Look at what she's actually sending. A snap of her face with no text and no context costs her almost nothing. It tells you she's on her phone and thinking of you loosely. A snap that refers to something you talked about, a place you mentioned, a joke from earlier, or something she's doing that she'd only send to someone she's comfortable with costs her more, and that's a better sign. Also check whether she ever sends anything without you going first. If every snap is a reply to one of yours, you're carrying the thread. If she starts conversations on her own, that matters more than how many she sends.

Next, see what happens when you answer with words. Some girls use snaps to start a conversation and then fill it with real questions. Others use snaps to avoid a conversation, and they go vague or short when you try to talk. Test this by writing a real sentence back, not just a reaction. Her reply length and whether she asks you something in return will tell you more than the number of snaps does.

Two kinds of reply tend to work. The first asks a specific question about her snap or her day, one she has to answer with a sentence rather than a reaction. You want her to say something you can respond to, so the thread has two people writing in it. The second makes a plan or proposes something concrete you could do together, even something small like coffee on Thursday or a walk near where she's been. That turns the snap thread into something with a next step.

You can tell a draft is the first kind if it ends with something she has to answer. You can tell it's the second kind if it has a time or a place in it. Leave out anything that sounds like a test, like pointing out how often she's been snapping, asking whether she's into you, or saying you were wondering why she's been so quiet. Skip flat jokes that only work as a reaction too, since she can't do much with them.

Timing matters more with snaps than with regular texts, because the thread is built around feeling seen during the day. If she sends a snap at lunch and you reply at 11pm, she'll read it as you not really being in the conversation. Reply within a few hours when you can. If you can't, send a short answer rather than leaving the snap on read for a full day, because a long silence after days of steady contact reads as pulling away.

If you've asked a question and she doesn't answer for a day, don't send another snap to fill the gap. Wait a day or two, then send one short message that's easy to answer, like a question about the plan or a reference to something you talked about before. If she replies warmly, keep going. If she sends back a one-word snap or nothing, the snap thread is probably all she wanted, and it's fine to stop chasing. Ask once for a plan, and if the answer is still vague, let the snaps be what they are.
