So basically, I had a crush on a girl since two years who happens to be my mother's student( as my mother taught her for straight 3 years until grade 10). I used to stalk her profile on weekly basis since two years and last March, I confessed her my feelings through a manifestation letter. The manifestation letter was so good that eventually she became interested in me and contacted me to know me better. Knowing the fact that I was her teacher's son and was a talented student, she asked me all my personal information. We became really close and communicated with each other on regular basis via video messaging in Instagram and in first week of April, she said she wanted to be in relationship with me. I hadn't excepted it (as she was my crush) and happily accepted. We wanted to meet non-virtually but due to Covid crisis, we couldn't. She was also interested in abroad studies and asked me everything about the US undergrad studies. Our house recently got hit by a Covid crisis and we lost our grandfather and she uplifted me during those times too.Everything was going good until last 15 days, after which she behaved indifferent and said that she used to like me although I should expect nothing from the future. She said she would be applying to Australia as soon as covid restrictions got over and insisted that we both should know we won't be together. I desperately wanted to talk to her by meeting so I requested for a date. She dismissed that by saying she was busy in households and would think about it later. Since last week, she started to text one word straight forward answers and being aware of the fact, I requested that we should meet in 2-3 days. She ignored my request and I couldn't help it. So, exactly 3 days ago, I requested her that we should just become good friends (informal breakup) and we would be talking in Viber. She accepted that and said she couldn't deny the fact she liked me, so we should keep talking as good friends. The day before yesterday right one day after the breakup, she contacted me in Viber and talked a lot about my father's surgery ( which happened recently) but yesterday once again she ignored my messages. So, I deactivated my viber, cause I felt as if she wanted to get help in abroad studies process and was playing with my feelings till now. I am feeling really low and depressed and  if she didn't want a relationship in first hand, she could have rejected me directly without giving me false hopes. She proved once again that humanity is cruel and I am getting mental depression hereby.
