I am the girl who can’t confess the love

r/

I am 23 and still single.
Since the school, I haven’t confess my love to anyone.The problem is I can’t flirt with the boys I liked. I am shy or i do have ego of not telling people I liked. Sometimes I initiate the conversation with the boys I liked but they won’t give me good response to continue the conversation .
There is one boy I liked from my college. And I literally thought he liked me too. Because we had a night out with friends and we both had a nice talk. He came and sit with me and I was all delusional.
It has been already 2 years and still had a crush on him. I try to talked with him but he shows he is not interested and I don’t want this feeling . what should I do to forget him or to get him?????
