Mad

Hello I am a 24 F and very hurt / not happy , I started talking to a guy on here two days ago . Every thing seemed going well then today he called me for a while , and hung up on me and gave me some dumb excuse why he hung up on me . then hours went by with out hearing from him then later I received a text from him saying that we weren’t gonna work out …. I don’t understand what I did wrong or what I said to make him not want me any more ?
