Shy Engineering Student: How to Make a Move on a Classmate?

Dear love guru, Hope u are doing well.  This story starts in 2018 when I was in my 12th. I had a huge crush on this junior girl. This girl is very intelligent and she used to get very high marks. So I took that as an inspiration and started working very hard on my academics. I started to read like a maniac and that worked and I got seat in a very prestigious college hoping she would get the seat in the same college but unfortunately she got seat in other state. I was disappointed. I was shy and never talked to her in my 12th and thought I lost my chance of talking to her ever again. But fortunately after a year, I found her insta and mustered my courage to chat with her.  Although it was awkward initially, we became good friends (I guess so) and used to chat almost daily. She is really a charmer and she chats so nicely. She is a great friend but I never had courage to say about my feelings. She used to talk about her friends, her new college and her cats and so many things about herself and as I am her senior, I used to guide her and talk about my daily experiences. We had great time talking to each other on insta, WhatsApp and even snapchat. Heck we have a Spotify playlist Collab and she even included me in her private Instagram account as a close friend (u know that girls do have spam accounts for close friends) and I was wondering whether I'm just another friend or close friend or anything more.  This continued like for many months and we chatted very well in the lockdown. I never met her or called her, we just chatted( I'm a shy guy and not so good at talking to girls). Feelings aside, she became a really good friend to me and I don't have many friends. I never said her about my feelings, fearing it would destroy this great friendship I was having. But recently she was not responding properly to my chats( I never misbehaved in the chat ). I do believe she is seeing a guy whom she met recently but I don't know whether that is a relationship or just friendship.  I was disappointed but hey it's her life and I was u know just continuing my life feeling sad sometimes or just trying to forget about her. And recently she completely avoided my messages and I was so hurt(I do have some self-respect right). U could say this as a one side love story. But this is so hard. After all she is my first love and this started affecting my academics. Should I move on or should I just continue trying to talk to her so that hopefully she will talk to me like she used to before. I don't have any problem continuing but sometimes I feel what's the purpose since it is going nowhere.  Please give me any valuable suggestion. Sorry for the long story Thank you  

Hello sir. I am a first year engineering student. Till 12th I studied in a boys school. Due to this I feel very shy with girls. But now, as I am in college, I found a girl in my class with whom I am in deep crush. I don't understand how should I approach her? How to make her my friend? Sometimes, it feels like the feeling which I have for her, she might not have the same for me. What should I do ?

I like girl from my previous office I send her Instagram request to follow her but she is keeping it pending
