10pts . Hes been ignoring me !!?

Okay. I was talking to this guy for about a month. He approached me . At first I wasent interested because he's older meaning 55 and im only 22 but he was attractive so I gave it a shot. During the time we been talking he rarely txt me or called. He would always make plans to meet up with me but somethin always comes up. Mind you his work schedule was from 4am to 5 pm. I work overnight from 10pm to 6am. So I get he would be tired. But this man couldn't possibly be that damn busy not to call me or txt me the while day right ?? I was getting mixed signals because when we would see each other on the bus he would be all up on me and talk dirty to me but then I won't hear from him unless I txt him. Now his schedule changed and he doesn't drive the bus I get on now. I haven't heard from him not once in over a week. Im pissed off about it and just wanna know why. I know in might think he's married . He did say he was before. he said that he doesn't wanna waste my time but what does he call this ??? Am I wrong to txt him and curse him out ???
