Your looking ? but don't communicate !! Online Dating

So as you may know most of you looking for someone to be in your life a partner a love a companion we go online shopping as i call it , because the first thing men notice is the pic and then a short conversation , then exchange numbers text a few times then met up and then say to one another "it was great meeting you lets do this again? ok i get it if your not interested that's all fine , but don't keep a girl thinking your into her when your not!. Why do people do that . and whats even worse is when you see them online after you've met? just be honest with one another . Don't play the "waiting for the next BEST THING"and keep one strung along that's hurt-full and cruel.
