Had a really good friend of same gender from choir. We used to sing together, do everything together. I texted her 24/7 and have been in close contact for around 3 years or so. Recently I've been asking her out to karaoke but she said she got some project to do in poly. Nevertheless I still contacted her and call her while she is apparently or so in lecture or in class having discussions/tutorials. then she began to block me for no reason, on WhatsApp, telegram, twitter and even Facebook after me trying to contact her. I even called her sister but to no avail. What to do? I lost a friend and it's been literally a week since I messaged her, take in mind that I text her literally every day but maybe she's mad at me idk? Pls help
