He dumped me after one date and I wish he had ghosted me instead.

I was talking to this guy I met online for a week. We got on super well and the conversation was amazing. We went on a date and it was one of the best dates I’ve ever been on. It was super comfortable, easy, conversation flowed and we were very attracted to each other. We spent the night together and he asked me out on a second date. As we were getting closer to seeing each other again he cancelled the day before. I didn’t think much of it because he was still messaging me frequently. Then the day after we were meant to meet I get a message from him saying “Basically I’m a really honest guy and I don’t like leading people on. I met a girl yesterday and we clicked really well and we’re going to go out again this week. I really enjoyed the time we had on our date so please know that it’s nothing on you I just don’t like dating multiple girls at the same time. I hope you understand.” This message literally broke my heart. I felt like I was going through a two year breakup. I cried called my best friend and my mum even though I had only met this guy once. Am I crazy? Is this a normal reaction? I honestly think I wouldn’t be hurting so much if he had just ghosted me and now I’m terrified of dating again.
