If she doesn't like you, then why did she let you wait until you came back? That's because she's afraid you won't come back if you leave. Of course, this does not rule out euphemistic refusal. So I said it was possible.
During the holiday, you should pay more attention to her and let her feel your presence. If she really loves you, you should pay more attention to her so that her heart will not fail and her feelings will not fade.
But you know, any relationship will fade. I didn't mean that, just not as passionate as before.
