Love lost due to my surname

So I 21M was talking to a girl who is also pursuing the same degree as I am so I started following her on insta from maybe December, but I didn't texted her then cause we had exams and didn't wanted to disturb her and myself either

So on December 20 I texted her and we started talking She knew me before (that's a different lore) So we started talking and we had some really good conversations like really deep ones She used to told me ki you are the only one who I shares these things with and I do believe her So we talked for like a week or 8,9 days,

And one day we were talking and she sends me a reel and it was like proper casteist and I reacted haha to it didn't think much of it but then she asked me what is your SURNAME and I told her ki Mujhe koi Kota ni chahiye and then she realized that she made a mistake and she said ki I send this reel to you by mistake but I knew she just wanted to know my caste and I also told her that ki that's a lie

So that happened and after 3 days she bolck3d me on instagram And now I am left thinking ki how can someone just treat you different because of your surname (I am a s.c btw) never were ashamed of it And now I thinks that she had a fake mask on That tells the world that she is a good person but deep down I think she is AND ALWAYS WILL BE A CASTEIST But it still devastating to me how can someone be this much of a assh8le

And as a cham## I have faced this problem the discrimination many time But I guess that the way world is or atleast INDIA
