Why does she seem to be playing games with me?

One vague reply tells you very little. Look at how she behaves across a few days. If she answers within an hour some days and disappears others, that usually means she texts when she's free and not thinking about you much. If she sends long, warm messages and then one flat one, she may be warm but unsure about meeting. Pay attention to whether she asks you questions. A person who is interested asks about your life, even a little. A person who is mostly just keeping a line open rarely does.

The mistake is to treat her short replies as a test you have to pass. That turns the whole thing into a game you're already losing. Instead, notice what she gives you freely and what she only gives when you push. Free effort is the real signal. Effort that appears only after you chase tells you she's responding to the chase, which is not the same thing as wanting you.

When she gives you a noncommittal answer, the best move is usually a short, concrete follow-up that is easy to say yes or no to. Name a real time or place, or ask one simple question about something she mentioned earlier. Keep it light enough that a bored reply is still an easy reply. Avoid stacking two asks in one message, because that makes it feel like a negotiation. Your reply should make a yes take one word and make a no cost her nothing.

What you want to avoid is anything that makes her manage your feelings. Apologies for being too much, jokes about how she's ghosting you, or long explanations of why you're interested all push the decision onto her. A clear, low-pressure message puts the choice back where it belongs and lets her show you where she stands.

Timing does more here than wording. If she has gone quiet after your message, one follow-up is fine a day or two later, sent in daylight and short. Do not send a second one a few hours after that, and do not check her profile to see if she's online. If she doesn't reply to the follow-up either, the honest read is that she's not pursuing this right now. Let the thread sit. You can come back in a week or two with a fresh, low-key message if you still want to, but treat that as a new start, not a continuation.

Stop when the conversation stops producing anything. If you're the only one asking questions, or every reply is a single word after several tries, the thing is over even if she hasn't said so. Ending it cleanly is better than trying to keep it alive with more messages, and it leaves you free to meet someone who is actually interested.
