I met a guy in social setting twice , he gave me lot of attention without any follow up , later when I messaged him , he left on read. I'm stuck. Why?

I come from a very conservative family , also never had guy friends in life. I live with my mom and sister separately, my mom left my father because he was a womaniser, he later abandoned us and lived his life selfishly, I had very less friends, Though I look good I get hit on by guys , but I Have low self esteem , low self confidence and self worth issues , Iam a pick me girl. I walked away from people played me and breadcrumbed me. I have history of toxic family dynamics, my mom is the only care giver. Due to my issues iam still living a mediocre life and no direction in life.

In a social interaction , the entrepreneur who is our senior and I shared glances, finally he took lead and we had great conversation, he told me a lot about his professional achievements, bragged about his background, later in second interaction at a lunch , it was a group setting, this time he told about his dating life his ex , he only showed me his personal diary in which he wrote feelings for her , told a lot about him and her, showed me a song he wrote and released on youtube , later we discussed on multidimensional different topics and our conversation went on.

At first interaction he asked my instagram I'd I deleted my socials so I said the same. Later we didn't got connected. We only met twice.
( In May this year )

I used to stalk his social media accounts secretly through a fake accounts since then , later I requested connection on LinkedIn to both his accounts in June , which he accepted, later after few months in Oct , I dropped a message regarding any internship opportunities, he left message on read and didn't reply. Why did he give me lot of attention in person , made me feel seen and heard for the first time in life , validated me. He is my limerent object. I cannot get over him. Was it love bombing, he gave me lot of compliments too. Was he a narcissist?
