Guy any suggestions

So this is about my friend whose my classmate and she’s been ignoring me for a while . Obviously in WhatsApp we do talk good in uni but in WhatsApp she replies like after fkin 10 hrs . I thought maybe she’s busy but I posted status few time in an hour of interval and she sees it and check in uni too she open my chats reads it and damn no reply . Well I got no idea when did I do anything wrong cause we don’t talk much like before other then having some work and also I dunno what to do . Should I start ignoring her or I will be myself ?
