Is she playing games with me?

I went out with this girl around two years ago but broke up after a month. We’ve always stared at each other ever since then.

I decided to message her again and she was very interested, giving me positive signals.

However, she slowly got worse at replying, going from multiple texts a day to not even opening my message in two days in a matter of a week.

I’ve seen her around my school where she still glances and stares at me, so there’s still an attraction there.

She never did this to me when we dated. Is she playing hard to get or doing something else?
