Pls advice

I am a 19 year old guy from Mumbai pursuing CFA while actively trading and investing in the markets. I assist my dad in his business play sports and stay focused on personal growth through certification courses. I believe I am in my peak development phase emotionally aware driven and self improving though I admit I have a fragile ego. I do not expect much from a partner just someone who is loyal transparent respectful and emotionally supportive. I am the kind of person who never checks your phone or messages I just want peace and honesty. I dream of being with someone I can sit beside in silence visit temples with weekly and share positive energy. I know it is hard to find true love in this generation but I still believe it exists. I met a girl 19 from Vapi who recently moved to Mumbai to pursue finance. We connected through a CFA community group and initially bonded over solving her doubts. After the exams our chats turned into long late night calls often 2 to 3 hours and I began to like her genuinely. She is smart well mannered mature and respectful. We never fought and she always shared everything with me the good and the bad. We flirted and connected deeply. In the beginning she used to reply instantly to messages but now even when she is online she does not bother replying. It feels off especially because she had once told me she had very few friends but now I see she has many guy friends which contradicts her earlier words. I do not have a problem with that but I do notice the shift. Today I had a certification exam from 2 PM to 4 PM. We were talking until 4 AM the previous night. I failed the exam completely my fault I was not prepared. But what felt strange was that she did not even wish me luck not a single all the best which she had never skipped before. Since the afternoon she has gone silent. I saw her online multiple times but she did not text. I called twice just to check if she was okay because she is new in the city and I naturally care more in such situations. At around 1 30 AM I called again. This time her friend picked up and said woh bahar gayi hai. But in the background I clearly heard her saying shhh and that genuinely hurt. I have always told her to be blunt with me I hate fake niceties or sugarcoating. If something has changed I would rather be told honestly. She once told me her ex was a known playboy and even after knowing that she chose to be with him. It makes me wonder do girls genuinely prefer guys like that. I do not know what is going on anymore. I do not expect a girl to leave everything for me but I do expect honesty consistency and boundaries. I have shown nothing but care and respect. I do not deserve to be ignored without explanation. I am not perfect but I am real. Maybe that is not enough in today’s world.
