He said I was a mistake?

I have been talking to this guy that I met on a dating app for the last two weeks all of our conversations have been awesome with little sexting.... we were supposed to meet last night but I had backed out because I had other plans with my friends... he said it was fine so we rescheduled for Monday. We have never met before so this would have been our first meeting.

Last night when he went to bed he told me good night and how comfortable he was with me and how he was so lucky to find a girl like me

I woke up this morning with a message that said I’m sorry you are mistake and I was just trying to find myself by talking to you

I’m kind of confused what he meant because he blocked me everywhere so I have no way to get in contact
