Guys, What should I do? Give up or not?

It was about 10 months ago in August 2022, as I was going through insta stories I came across a series reel on someone's story and getting interested to watch it I immediately replied to the insta story and asked him about the name of the series. He then immediately replied me the name of the series. After that I thanked him and he said welcome and started having a conversation with me. The conversation was out of the box for me as I just casually messaged him for the series name. He was the first one started asking questions to me about myself and we started having long conversations. The one thing I knew conversing with him is that I am completely out of his league. He is an extrovert and so handsome, he likes blue color, he likes traveling, he is so hardwoking, etc are the things I discoverd of him. Then after chatting for few days we came to know that we both live nearby so we met and I remember he was wearing white shirt and we went on a long drive. We had such a nice conversation during the entire long drive. After that we went on 4 more dates. All the dates with him were so good as he knew I was an introvert and never knew about places in our area; he initiated to make me get acknowledged with the places and food near our area. He shared about his life, future planning and his secrets with me and with the flow I too told him my secret. He got job and I was the first person he informed. Almost 2 months we were on good terms but after that he started ignoring me. On new year I wished him and he too wished. Then on march 18 i wished him happy birthday and he thanked me. Thats it! I made a poem and digital art hard copy for him on his birthday but he never came. Although I asked him few times to recieve it, he never came. I prepared the gift with hardwork and love. I thought after giving him gift I'll confess and tell him I am giving up on him but that day never came. What should I do? I knew I was out of his league and it kills me falling in love with him.
