Come on, you and I know both that girls check their phones all the time. There is a reason why she did not reply yet - most likely its because she is not that into you. Push her by stalking her on the phone - even though you have reached out to her before without any answer - and you shut that door forever. I would just shut up for now and try hitting on her at a different time, in a different place.
Lul i met her 4 years ago and she was tryna **** me but i was a virgin and denied her. Ik she hasnt opened it cuz its snapchat and it would have said message opened lol. But yeah who knows maybe shes choosing not to open it
Can't you just put your phone in airplane mode before actually opening the message? Not sure if it works, but anyway: you seem to be thinking too much about this already which - if you decide to call - would make you lack that eazy peazy and charming coolness on the phone. I wouldn't do it. Call her later on - once you reach a state where you genuinely don't care at all. (I assumed you can't fake it at this moment as you stated you were shy on the phone - apologies if I misinterpreted that)
If you currently have too many women chasing you, calling you, harassing you, knocking on your door at 2 o'clock in the morning... then I have the simple solution for you.
Just read my free ebook 22 Rules for Massive Success With Women and do the opposite of what I recommend.
This will quickly drive all women away from you.
And you will be able to relax and to live your life in peace and quiet.
No, you just go out and do your thing and if she hits you up later invite her down.
