Dating of Someone who's entire personality is a concept of streamers, online persona and deeply flaw

Too bad, I really liked that guy, he was my ideal boyfriend, he was emotional, he was sweet, and had good morals. I was looking for someone who isn't similar to my dad, who was mean and alcoholic. I wanted a guy who's a complete opposite, someone who's kind, good morals, sweet and cute. We had similar interest, and it feels like seeing a male version of myself but then that guy did a complete 180 personality and turned out to be a complete menace behind the scene. For starters:

He asked me to move in his apartment prior 1 week of getting to know each other. I thought he was joking, so I brushed him off.

He played video games all day. He had this streamer personality where he's constantly performing jokes. He has a problem with that and I truly dislike him, he couldn't separate his youtuber personality to his real identity. Turns me off so fast. I'm talking to you, & don't want to be treated like the same "fans" Or "viewers"?

He forwards our private convo to his friends and kept asking "How'd she do?" Like he needs some sort of male validation, asking them what he needs to say to me, I'm dating you, not them.

He wants me to chase him, he wants to be a princess, he wanted me to do everything for him, from chores, to food, to wedding, all that while he does nothing. He expects me to get down on one knee and propose to him. Mind you, he's the one who wanted me first.

He talked to numerous discord vtubers and e girls all day, I saw him 17 hrs discord voice call. That's when I finally snap, no more nonsense for me. I told him, "I truly liked you... But as a friend. Never liked you that way..."

He snapped, he started going off, he had a major crash out, he blocked me in all social media, from twitter, to genshin impact, facebook,tumblr, tiktok, instagram, to youtube, to GMAIL, to every socmed he had.

He started venting to his Twitter and said, "no one will like you for your childishness, I'm the only one who truly see you for you when everyone else hated it, I'm the only one tolerates you, you never had a boyfriend."

He started asking his friends to get on his side by completely telling me I was manipulative, I was the witch.

When I looked at his account one last time, he started posting racist rants and memes, exposing his bigotry and ugliness after I rejected him.

Never give dating a try, my friend. It's scary
